What are wagon tracks in welding?

Wagon Tracks – Also called worm tracking, these are weld defects caused by hydrogen that has been trapped by the freezing slag. They appear when a bubble flows into the weld puddle and evaporates into the atmosphere, and are typically caused by excessive voltage. You can’t get the job done without the proper equipment.Click to see full answer. Beside this, what causes worm tracks in welds?Worm tracking are marks on the surface of the weld bead that are caused from the gas that is created by the flux in the core of the wire. The gas causes worm tracking when there is excessive voltage for a given wire feed setting/amperage.Likewise, what is groove weld? A type of weld that consists of an opening between two part surfaces, which provides space to contain weld metal. Groove welds are used on all joints except lap joints. what is downhill pipe welding? On thinner-wall pipe, downhill welding enables operators to run “hot and fast,” increasing productivity compared to welding uphill, which is required on thicker wall pipe to increase heat input to ensure complete penetration.What is ARC force in MIG welding?Arc force is a temporary increase of the output current during welding when the arc is too short. This feature supports production with consistently excellent arc performance. It also enhances simple position welding making the job easier.
