Welding accessories in a wide range of welding applications, welding accessories, such as the production process of a length dimension have certain requirements, then we should be how to properly use it.
Peening the weldment, in order to prevent Shot drill weld seam must be welded inside and try to avoid the internal chamber and the lumen. If you must have an inner chamber and cavity structure, it must be pickled, in order to reach the surface rust grade quality. Welded structure length dimension tolerances, dimensions and geometric tolerance values for the length of the dimensions of the welded parts and welding components.
Welded structure length dimension tolerances, dimensions and geometric tolerance values for the length of the dimensions of the welded parts and welding components. Weldment ordinary low-alloy structural steel, and we must follow the parts to be welded carbon equivalent and alloy element content, thickness, and requires the use of steel structure parts were preheat and post-weld treatment.
A sealed cavity weldment, before the heat treatment, should be in place working Φ10mm hole spacing plate to the cavity and the outside world. Need outer wall of the borehole, to re-plug in after the heat treatment.
