Welded part Casting characteristics and main product
Welded Part Specific Parameters
Main process and Technical quality Control content of welded parts production.
1.Main process and Technical quality Control content of welded parts production.
2.Select the appropriate profile materials according to the requirements of drawing materials, Select the corresponding profile materials and specifications in China according to the requirements of drawing materials. The welding materials commonly used are: carbon steel, alloy steel and stainless steel. Different size profiles are: sheet, round steel, steel pipe, channel steel, angle steel, square steel, I-beam and so on.
Select the appropriate equipment and process for profile cutting based on the size of the drawing structure. The methods of cutting are usually as follows:
Sheet: shearing machine or WEDM
Thick plate: WEDM or gas cutting
Round steel, steel pipe, channel steel, angle steel, square steel, I-beam: gas cutting or sawing machine.
a.Select suitable welding equipment and welding materials (electrode, wire, etc.) according to material requirements
b.Determine the appropriate welding process (including welding material specification, welding current, weld form, etc.) based on the specification and product size of the profile, If necessary, the process evaluation test can be carried out first.
c.Check whether the weld quality and structure meet the drawing requirements after welding.
5.Post welding treatment
a.After welding, the product is repaired and shaped.
b.Perform stress relief annealing heat treatment if necessary.
Machining based on the drawing.
Inspection based on to the requirements of the drawings and delivery after acceptance.
