Equipment manufacturing, welding process design is very important, technical stronger, which requires strict requirements of welding technology, we look at the weld process design technology generally need to pay attention to what matters:
1. The design of the weld shall comply with the principle of "equal strength", that is, the strength index of the weld shall be greater than or equal to the strength of the base material; In the weld filler material selection, welding procedure and heat treatment process of formulation, welding quality control, structural design and stress of the weld joint control, etc., shall ensure that the carrying capacity of welding seam and heat affected zone is not lower than the parent metal.
2. In the butt weld with varying thickness or width of the steel plate, the slope Angle of no more than 1:4 shall be made on one side or both sides of the plate.
3. For angular weld bearing dynamic load, full penetration structure shall be adopted.
4, when the weldment is not perpendicular with bevel Angle of welding seam, should not be less than 60 ° Angle between two components.
Basic requirements for amusement equipment weld:
1. There shall be no defects on the surface of the welding seam, such as welding leakage, burning through, cracks, unfused, unextinguished, unfilled, arc pit, serious edge biting, and visible pores and slag inclusion.
2. The weld and the base material should be smooth transition.
3. All welding slag and welding tumors shall be cleaned.
