co2 welding procedure chart for dummies


Welding Procedure Specification WPS may be generated by an authorized person i e CWI and then submitted to the NCDOT Materials & TestsUnit Steel Section at A Park Centre Drive in Kernersville NC phone for approval in the event that theSolution When you’re making a welding pass be sure to use enough weld metal to completely fill the space between the previous bead and the one you’re working on Also make sure that you deposit the weld metal all the way to the very end of the joint and if there’s a crater at the end fill it Cause Dirty surfaces Mar 26 Welding is more than dragging a welding rod across a piece of steel and gluing it to another one The process begins with properly fitting and securing the work pieces or metal to be welded together For thicker pieces you may want to grind a bevel so subsequent beads can be placed in the groove to fill it completely with a solid weld welding operations are considered ‘‘skilled trades ’’ and the labor to perform these operations may be scarce 2 Most welding processes are inherently dangerous because they involve the use of high energy 3 Since welding accomplishes a permanent bond between the components it does not allow for convenient disassembly Aug 08 That all sounds fine unless a welding engineer or procedure has done all of that work for you If not then it is time to look at the next section MIG Welding Charts Settings and Guides MIG Welding Charts Setting Guides and Exact Answers Finally if you need some exact answers and guidance then you can read this!To achieve safe working conditions in the metal fabrication and welding industry all personnel should be able to recognise the hazards which apply to their particular occupation Welding operators must also know the correct operating procedures for the equipment An operator can be subjected to many safety hazards associated with the industry AsFusion welding The most widely used welding proc esses rely on fusion of the components at the joint line In fusion welding a heat source melts the metal to form a bridge between the components Two widely used heat sources are Gas flame The molten metal must be protected from the atmosphere absorption of oxygen and nitrogen leads to a Co2 welding is the welding technique also used in most of fabrication industry Difference between co2 and arc welding arc welding flux coated electrode are used KOBELCO 神戸製鋼
