How To Remove Welding Joints. You might need to build a wood _not metal frame to wrap the leads around to make dragging the coils easier. Before welding even takes place particularly with carbon steel the workpiece should be cleaned to remove any mill scale formed from the hot rolling manufacturing process - mill scale can interfere with the quality of the weld.
Welding pipe can cause the pipe to deform in strange ways because of the curved surfaces on which the stresses act during the heating and cooling process. Its a good idea to Carefully finish grinding the last little bit of weld down using a cut-off wheel on the grinder. Many fabricators will fill the pipe with fine-grained dry sand and close the ends of the pipe.

Keep the wheel perpendicular to the surface of the metal. Step 4 Allow the wheel to cut down through the metal then push the saw or grinder away from your body in a straight line to cut all the way through the piece. Ignoring these steps hurt your chances to make a good weld the first time. 6 Keep the weld axis in horizontal by positioning.
