Are very thin workpieces difficult to weld? For example, for a smoke duct made of galvanized iron like the one below, it is necessary to weld several φ10 steel rebar onto the outside – is welding that difficult?
Use TIG welding, and it’s best to have an experienced worker do it.
Because the workpiece is too thin, the heat from the welding torch can easily burn through it.
It is prone to collapse during welding and deformation as well; welding galvanized parts generates a lot of smoke. Generally, for such things, a steel bar is used as a reinforcement element, with holes drilled and rivets inserted.
It is best to use stud welding. For galvanized workpieces, zinc has a low melting point and volatilizes heavily, which severely affects arc welding.
It’s not difficult using MIG welding; weld on the side of the rebar.
