Means of reducing and controlling weld distortion are described, covering b) tack weld one end, then use back-step technique for tacking the rest of the joint. It is a weld progression utilized to minimize distortion. Backstep welding is a technique to avoid distortion while welding on thin sheets. This technique involves a continual stalling of the forward travel motion by traveling backwards slightly, into the previous deposited weld. This technique has two.
