Storage of stainless steel parts: there should be special storage rack, storage rack should be wood or surface painted carbon steel bracket or cushion with rubber pad, to isolate from carbon steel and other metal materials. Storage, storage location should be easy to lift, and other materials storage area is relatively isolated, protective measures should be taken to avoid dust, oil, rust pollution of stainless steel.
Stainless steel lifting: special lifting gear should be used when lifting, such as lifting belt, special clip head, strictly prohibit the use of wire rope to avoid scratching the surface; And in the lifting and placement, should avoid impact knock caused by scratch.
Stainless steel transportation: transportation, the application of transportation tools (such as car, battery car, etc.), and should be clean with isolation protection measures, to prevent dust, oil, rust pollution of stainless steel. No dragging, avoid bump, scratch.
Stainless steel processing
1. Processing zone: the processing area of stainless steel parts should be relatively fixed. The platform of stainless steel parts processing area should take isolation measures, such as laying rubber pads. The location management and civilized production of stainless steel parts processing area should be strengthened to avoid the damage and pollution of stainless steel parts.
2. Blanking: the blanking of stainless steel parts by cutting or plasma cutting, sawing, etc.
A. Shearing: When shearing, it should be isolated from the feeding bracket, and the hopper should also be covered with rubber pads to avoid scratches.
B. Plasma cutting: After plasma cutting, cutting slag should be cleaned up. When cutting in batches, the completed parts should be cleaned out of the site in time to avoid the contamination of the workpiece by cutting slag.
C. sawing cutting material: sawing cutting material, clamping should be protected by rubber, sawing should be cleaned up on the workpiece oil, residue, etc..
Mechanical processing: stainless steel parts in the car, milling and other mechanical processing should also pay attention to protection, the completion of the work should be cleaned up the surface of the workpiece oil, iron and other debris.
Forming processing: in the process of rolling plate and bending, effective measures should be taken to avoid scratches and creases on the surface of stainless steel parts.
Welding of stainless steel parts
Riveting: stainless steel parts in the group, should avoid forced assembly, especially to avoid flame baking school assembly. Group or production process such as temporary plasma cutting, isolation measures should be taken to avoid cutting slag pollution to other stainless steel parts. After cutting, the cutting slag on the workpiece should be cleaned
Welding: stainless steel parts before welding must seriously remove oil, rust, dust and other sundries. When welding, try to use argon arc welding. When using manual arc welding, small current and fast welding should be used to avoid swing. It is forbidden to start arc in non-welding area, and the ground wire is in proper position and firmly connected to avoid arc abrasion. Welding should take anti-splash measures (such as whitewashing methods). After welding, use stainless steel (not carbon steel) flat shovel to clean slag and spatter thoroughly.
Multilayer welding: when multilayer welding, the slag between layers must be cleaned. Multilayer welding, should control the temperature between layers, generally not more than 60℃.
Weld: weld joint should be polished, weld surface shall not have slag, porosity, edge bite, splash, crack, not fusion, not penetration defects, weld and base metal should be smooth transition, not lower than the base metal.
Orthopedic: stainless steel orthopedic parts, should avoid the use of flame heating method, especially do not allow repeated heating of the same area. When orthopedic, try to use mechanical devices, or with wooden hammer (rubber hammer) or cushion rubber pad hammer, hammer hammer is prohibited, in order to avoid damage to stainless steel parts.
