Equipment for welding equipment

1. The design of the weld must comply with the principle of "equal strength", that is, the strength index of the weld must be greater than or equal to the strength of the base material; in the weld filler material selection, welding process and heat treatment process development, weld quality control , Weld joint structure design and stress control, etc., should ensure that the weld and heat affected zone carrying capacity of not less than the base metal.
2. In the butt welds where the thickness or width of the steel football zone for trampoline, the slope of the plate shall be not more than 1: 4 at one or both sides of the plate.
3. Weld joints to withstand dynamic load, should be used throughout the welding structure.
4. When the weldment is not perpendicular to each other and the use of bevel angle welds, the angle between the two components should not be less than 60 °.
