Apr 11 Tack welding is the best way to hold the metal in place before you fully weld it to the original metal Tack welds are simply small welds that barely penetrate the metal and aren’t pushed or pulled to form a bead Tack weld different areas of the joint about an inch apart This will hold it in place and allow you to weld it properly Complete The welding coordinator prepares a preliminary welding procedure specification pWPS which is an initial proposal for carrying out the procedure test For each joint configuration either butt or fillet weld consideration is given to the material grade and thickness and anticipated fit up tolerances likely to be achieved in practice Due to the poor adhesion property of some weld through primers it may have to be removed from all exposed surfaces after welding before applying other coatings and sealants 8 Apply the proper adhesive to the roof panel roof bows and reinforcements with the proper caulking to restore strength and noise reduction 6 Fillet Weld Symbols Fillet welds are one of the most common weld types in the industry This weld is used when the joint has two members coming together to form an intersection of commonly 90 degrees These welds can be applied on varying angles but this would be the most prominent A fillet weld symbol can be used with an arrow side below However most fillet welds are not transferring full loads rather they are there to add rigidity AWS D1 1 provides minimum fillet weld sizes for a given material thickness For 1/2 inch the minimum fillet weld size is 3/16″ Keep in mind that penetration into the root adds to the strength of the weld So you welding procedure matters Section WFP 2 01 – Welding Fabrication Procedure Rev 1 10/27/06 Attachment 2 ASME B31 3 “Process Piping” Acceptance Criteria Page 3 of 4 FILLET WELD PROFILES AND SLIP ON / SOCKET WELDED FLANGES WELD PROFILES Equal Leg Fillet Weld The “size” of an equal leg fillet weld is the length of the largest inscribed right isosceles triangle Develop a repair welding procedure – Now that you have all the details regarding the failure mechanism understand the service requirements and know which code or standard to follow you can craft your welding procedure Your welding procedure shall include joint details including joint preparation welding process filler metal preheat and Jan 27 Work angle With wire welding hold the gun at a 10° to 15° angle into the direction you are pushing the weld With stick welding maintain a 20° to 30° lead angle in the dragging direction With a fillet tee weld hold the rod or wire regardless of weld process at a 45° angle between the two pieces of metal the metal that is being welded and the joint type i e groove fillet etc dictates the welding parameters and the procedure that needs to be followed to obtain a sound weld joint Typical Arc Welding Processes Shielded metal arc welding SMAW Shielded metal arc welding which is also known as stick welding is the most widely used process

These welds provide smooth transition to weld metal after grinding Connected elements in a T joint should be brought into as close of contact as possible before joined with fillet welds The increase in gap leads to a decrease in throat and is not apparent visually backing ring or strip or it shall be weld metal deposited by another process or electrode type or the joint shall be made from both sides of the joint i e backwelded Fillet welds are considered welding on backing and all sizes of fillet welds may be made using any NCPWB WPS on any thickness or diameter base metal fillet weld The type of weld to use is determined by the location of the joint on the vehicle and whether the repair area is structural or non structural The steps to prepare for a weld are 1 prepare the surface by removing paint under coatings rust dirt oil and grease 2 apply a weld through primer to the surfaces to beFillet welds are one of the most common weld types in the industry This weld is used when the joint has two members coming together to form an intersection of commonly 90 degrees These welds can be applied on varying angles but this would be the most prominent Volume 2 Welding Fabrication Procedure Rev 1 10/10/06 WFP 2 04 – AWS D1 1 Structural Welding Steel WFP 2 04 AWS D1 1 STRUCTURAL WELDING STEEL 1 0 PURPOSE AND SCOPE A This welding procedure governs the welding of components to the requirements of AWS D1 1 Reference 1 The Code edition and addenda for this procedure shall be the9 1 GMA MIG Fillet Weld Procedure To make a GMA MIG fillet weld 1 Clean the mating surfaces to remove oxides and any other residual contaminants that could adversely affect weld quality 2 Clamp the mating surfaces tightly together 3 Make sample test welds on scrap pieces of the same alloy and thickness as the parts to be welded Feb 01 Take the time to tell others that they should not be in this area while you are welding unless they have the proper eye protection Step 2 – Clap Once the area has been set up you are ready to get the 2 pieces of sheet metal that you are welding clamped together Make sure that they are fitted together tightly and have a flush seam Jan 20 The best two electrodes for welding auto body sheet metal is either ceriated tungsten or thoriated tungsten Ditch a 1/8 inch tungsten electrode for something much smaller like 1/16 inch tungsten Because it will have you a lot more control over the whole process and it is more forgiving in case you do anything wrong be specified resulting in a weld that would otherwise be disallowed by Table 5 8 It is still important that good weld ing practices be followed when seal welds are made including adherence to the minimum fillet weld size Failure to do so may result in weld cracking or incomplete fusion defects

May 20 We are attempting to gather all required items to be certified by AISC American Institute of Steel Construction as a certified steel building fabricator and I ran across this requirement in the FAQ& 39 s where someone had asked if even the weld fillet gages needed to be certified here is the quote " 1 3 Do fillet weld gages used for AWS D 1 5 Section 3 6 1 1 in reference to fillet weld profiles The convexity of a weld or individual surface bead shall not exceed times the actual face width of the weld or individual bead respectively plus [ in] Mar 21 About 10 to 20 CFM at atmospheric pressure is a good range in which to work when you are welding body metal with to inch wire Practice and experimentation are your best guides in this matter Amperage settings are critical when MIG welding sheetmetal Amperage is set by setting the wire feed speed Jun 01 Lap joint also a fillet weld Angle the gun between 60 and 70 degrees The thicker the metal being welded the greater the angle You& 39 ll want to direct more heat into the bottom piece of metal when welding a lap joint A 60 to 70 degree angle is usually best A fillet weld shown here is one of the most common types of welds Pipe welding has four positions 1G the horizontal rolled position In this position the pipe is horizontal and it is being rolled so that you the welder are actually in a flat position relative to the pipe It& 39 s the easiest pip welding welding position 5G the horizontal fixed position 5G is a lot like 1G in that the pipe is in the Enter the date the welding procedure data sheet was prepared and the revision number Reference Standards Some welding standards that may be referenced are W47 1 – Certification of Companies for Fusion Welding of Steel W59 – Welded Steel Construction Metal Arc Welding W – Welding of Reinforcing Bars in Reinforced Concrete ConstructionSpecification and qualification of welding procedures for metallic materials Welding Procedure test Part 1 Arc and gas welding of steels and arc welding of nickel and nickel alloys Part 2 Arc welding of aluminium and its alloys Part 3 Fusion and pressure welding of non alloyed and low alloyed cast irons Fillet weld gages are one example of equipment used to demonstrate final acceptance of welds Only the gages used by personnel performing final inspection need to demonstrate traceability to a national standard " I have not seen these ever to have been certified Can anyone shed some light on where I could obtain a " certified welding gage" When a fillet weld is required on both sides of the reference line it is called a double fillet weld The vertical leg of the symbol will always be placed to the left regardless of which way the arrow is pointing Fillet welds may have a size associated with them
