As the arc. NOTE: Keep the arc gap from the tungsten to the work achieved when welding at to away from the copper. Copper and ignites the welding arc. Without fixtures, tack weld the joint every couple of inches and peen the tacks to remove shrinkage stresses. Finish the joint with a welding sequence designed to minimize distortion. A planned sequence of welding always helps control distortion.

The techniques used in mild steel welding can be used. Skip welding and back-step welding are recommended for light gauge steels. Low current and stringer beads reduce distortion by limiting the amount of heat at the weld.

Also, do not deposit excessive weld metal. It seldom adds to the strength of the weld and does increase heat input and promotes distortion. If a structure of heavy steel is not rigidly held during welding, many small beads will cause more total distortion than a few large beads.

Distortion Control in Ferritic and Martensitic Stainless Steels Since they have heat expansion properties similar to mild steel, plate structures of ferritic and martensitic stainless steels are designed and welded with about the same distortion controls and allowances as mild steel.

However, because they have lower thermal conductivity than mild steel, the heat remains concentrated in the area of the weld. This causes distortion problems in thin-gauge steel. This distortion can be controlled with suitable jigs and fixtures, proper joint design and a correct welding sequence. Society AWS — A5. Rods for Gas Tungsten Arc with filler material for welding.
