In the pursuit of manufacturing perfection, welding stands as a critical determinant of product quality and performance. The selection and execution of welding techniques require meticulous attention to detail, where each weld point embodies craftsmanship.

Modern manufacturing offers multiple welding process options, each with distinct characteristics and applications:

• Tungsten Inert Gas (TIG) Welding: Particularly effective for thin sheets, box structure exteriors, and butt joints. For medium-thickness plates, filler rods may occasionally supplement TIG welding. This method produces continuous fish-scale patterned welds known for both aesthetic appeal and structural integrity.
• Semi-Automatic (CO2) Welding: Commonly employed for fillet welds in medium-thickness plates, though it generates spatter and slag. CO2 welds exhibit fuller bead profiles with more pronounced surface characteristics compared to TIG welds.
• Filler Rod Standards: Typically, filler rods are used when material thickness exceeds 3.2mm for ferrous metals, 4.0mm for stainless steel, or 2.0mm for aluminum. However, exceptions exist for box structure exteriors, butt joints, or welds near apertures where TIG welding without filler rods may be preferred for functional and cosmetic considerations.

Fiber laser or YAG laser welding options are selected based on product geometry. Laser welding offers exceptional precision with minimal heat-affected zones and distortion, making it ideal for delicate components.

Manufacturing systems can automatically determine optimal welding methods (arc or laser) based on material properties, thickness, and product geometry. Repeat orders for identical parts maintain consistency by replicating initial order welding techniques.

Both stationary and bench-type spot welders are utilized according to product requirements. Stationary spot welding creates indentations at overlapping plate interfaces, while bench-type welding leaves no marks on electrode contact surfaces, though typically produces deeper indentations. Pressure application direction is determined by product geometry, with special requirements accommodated through specification notes.

Arc welding products maintain weld sizes (leg lengths) within these parameters:

• Common Materials (SPCC/SPHC, SECC, SUS304, SUS430):
  • Minimum reference: 0.7 × thin plate thickness (t1) mm
  • Maximum: 1.5 × thick plate thickness (t2) mm
• Aluminum Alloy (A5052):
  • Minimum reference: 3.5mm
  • Maximum: 10mm

Manufacturers guarantee reliable welded connections with rigorous quality controls ensuring components are delivered in optimal condition. While specific application strength warranties aren't provided, all welded joints undergo thorough inspection to verify structural integrity.
