View point of welding groove of S420M steel plate

When welding S420M steel plate and beveling one side of S420M steel plate, the thickness of S420M steel plate is 3-6 mm, and the viewing point of the beveling of S420M steel plate is 70 ̊; When the thickness of S420M steel plate is an even number of 7 to 10mm and 12 to 26mm, the viewing point of the groove is 60 ̊; If a piece of S420M steel plate is to be affixed to the bottom surface, the viewing point of the groove is 50 ̊. If both sides of the S420M steel plate are beveled, the viewing point of the groove is 60 ̊.

When S420M steel plate is welded at right angles and one side is beveled, when the thickness of S420M steel plate is 4-6 mm, the viewing point of the groove is 55 ̊; When the thickness of S420M steel plate is greater than 7-30mm and it is welded at right angles, and both sides are grooved, the viewing point of the groove is 60 ̊.

The viewpoint of the S420M steel plate groove is an important welding process factor that affects weld formation, welding dilution ratio, and the shape of the fusion zone, and even affects the stability of the welding arc.
