If two iron plates or stainless steel plates are used, the welded joint of the plates can be polished into a half slope, and the welded surface can be polished smooth (polished or turned) after welding, so that the weld can not be seen.

Note: 1. Before welding, tighten the two plates and fix them with a fixture to prevent welding deformation;

2. Do a good job in protecting the non-welded surfaces (perforated surface and back surface).
