How to Perform MIG Welding on Aluminum

Metal Welding, Materials, Technology Guide / By Supro MFG

In aluminum fabrication, MIG welding is a key process for achieving both structural strength and aesthetic appeal. The core challenges of aluminum welding lie in its unique physical properties: the melting point of the surface oxide layer (approximately 2050°C) is significantly higher than that of the base metal (approximately 660°C), coupled with high thermal conductivity and a high coefficient of thermal expansion. If not handled properly, this can lead to contamination of the molten pool, porosity, and distortion. As a trusted MIG welding aluminum manufacturer, we emphasize that successful aluminum welding processes begin with proper surface preparation of the base material.

Analysis of Sheet Metal Bending Radius

Technology Guide, Sheet Metal Bending / By Supro MFG

The sheet metal bending radius is far more than just a default CAD parameter; it is a core factor in cost control, structural integrity, and assembly accuracy. Although most designers default to the theoretical minimum of “1 times the thickness,” this often conflicts with actual economic realities on the shop floor—approximately 95% of parts with a thickness of 0.125 inches or less are formed using a standard 0.030-inch bending radius to avoid frequent die changes. Excessively small bending radii can cause material cracking and unpredictable springback, particularly in high-strength materials such as stainless steel or 6061-T6 aluminum. Conversely, overly large or inconsistent radii can compromise K-factor calculations, leading to distorted flat patterns and costly tolerance stacking during multi-component assemblies.

about electrolytic polishing stainless steel

Materials, Surface Treatment / By [email protected]

Polishing stainless steel is a common surface treatment process that not only affects aesthetics but also directly determines the performance, service life, and total lifecycle cost of stainless steel components. While traditional mechanical polishing methods are widely adopted, they often introduce defects such as embedded abrasive particles, microcracks, and uneven surface layers. These flaws not only compromise corrosion resistance but may also become sources of contamination. Electrolytic polishing of stainless steel, as an advanced electrochemical process, achieves microscopic surface leveling through a controlled anodic dissolution process. It selectively removes protruding areas, resulting in a microscopically smooth pristine surface. This polishing technique forms a thick, uniform chromium oxide passivation layer, significantly enhancing resistance to pitting and crevice corrosion. This is particularly critical in highly corrosive chemical or saltwater environments. Furthermore, electrolytic polishing fundamentally decontaminates surfaces by removing embedded impurities. Its exceptional cleanliness, low particle adhesion, and superior hygienic properties meet stringent FDA, cGMP, and SEMI standards. For complex geometries like tubing

How to Select a Power Source for TIG Welding Aluminum?

Technology Guide, Materials, Metal Welding / By [email protected]

During TIG welding of aluminum, welders employ high-purity argon gas, specialized tungsten electrodes, and strictly adhere to cleaning procedures, yet issues such as weld porosity, unstable bead formation, and oxide inclusions persist. The root cause lies in the mismatch between the power source output characteristics of TIG welding aluminum and the physical nature of aluminum alloys. The high thermal conductivity, instantaneous oxidation tendency, and low melting point of aluminum alloys demand precise heat input control and rapid dynamic response from the power source. Traditional base power sources provide only simple AC output for TIG welding aluminum, failing to balance cathode cleaning with heat input management.
