1) Straight weld
As shown, the shape of the welding seam of the product is a straight line, and the joint form is a butt joint, a lap joint, an internal corner corner seam joint or a lap welded joint. It is better to blow protective gas on the shaft side for a laser welding machine.
2) Plane closed graphic weld
The shape of the welding seam of the product is a closed shape such as a plane circle, a plane polygon, and a plane multi-segment line. It is better to use the coaxial protective gas method.
The selection of shielding gas directly affects the quality, efficiency and cost of welding production. However, due to the diversity of welding materials, the selection of welding gas is also relatively complicated in the actual welding process. It is necessary to comprehensively consider welding materials, welding methods, and welding positions. As well as the required welding effect, only through the welding test can a more suitable welding gas be selected to achieve better welding results.
