Do you know the principle of welding repair and correction process for stainless steel castings?

Stainless steel castings in the finishing manufacturing link can apply its grinding and polishing way to do a good job of cleaning the surface of the machine and equipment defects, casting in the grinding and polishing after its specifications also effectively apply its casting specifications of the size tolerance standards, usually deformation of the casting allows the application of mechanical way to do a good job of correction.
Stainless steel castings in the application of the link can be directly applied to its welding way to do a good job of repair, when the machine and equipment to apply its tungsten argon arc welding welding, its welding surface area and the depth of welding to apply its standards, the surface area of the machine and equipment welding refers to the surface area after expansion.

Stainless steel castings in the same place welding patch is not more than three times, the distance between the edges of the casting in the welding area, which involves the reverse welding area, remember that it can not be lower than the sum of the Truck Spare Parts Alloy Steel Precision Investment Casting Parts diameters of the two adjacent welding areas, but where the heat treatment and tempering state supply of the casting, after welding patching but also according to the original state of good heat treatment and tempering.
In the heat treatment and tempering of stainless steel castings but also to be able to do a good job of testing its mechanical properties, castings in the argon arc welding area surface area remember not to be less than 50px2, machinery and equipment welding area distance of not less than 100 mm, in the application may not go through its heat treatment and tempering, but a stainless steel casting remember not to more than 5 places.
In the good welding patch area is not to have cracks and not welded through the situation, casting in all a welding area is allowed to have a diameter of not more than 2 mm and not more than 1/3 of the wall thickness of the pore or the participation of three, machine and equipment edge distance of not more than 10 mm.
