Select the welding amperage based on metal thickness in 120v arc welding. For 2.0mm stainless steel rods, use 30-50 amps. For 4.0mm, apply 90-120 amps. Start with lower amperage for thinner metals. Use higher amperage for thicker ones. Follow this SMAW guide and ensure DCEP for optimal welding results. Conversely, thicker materials, such as those … Read more

In arc welding, the power supply activates the electrode near the base material. This creates an electric arc that produces intense heat. The heat melts the base metal and the electrode core. Meanwhile, the flux coating provides a shielding environment, protecting the weld area from contamination and ensuring a strong bond. The benefits of arc … Read more

Wire Arc Additive Manufacturing (WAAM) is a modern method for making large metal parts from materials like titanium and aluminum. WAAM delivers high deposition rates and strong mechanical properties. This economical manufacturing process builds components layer-by-layer, improving accuracy and part quality in additive manufacturing. Additionally, the document highlights economic advantages. WAAM can reduce production costs … Read more

Welding arc burn, or welder’s flash, occurs due to UV light from welding torches. It feels like sunburn in the eyes and can impact both. Symptoms include pain and light sensitivity. The cornea typically heals within one to two days without scarring. Wearing protective eyewear can effectively prevent this condition. The primary cause of welding … Read more

Arc burn is a welding defect. It occurs when the electric arc unintentionally contacts the base metal, like aluminum or steel. This contact creates burns on the hot metal surface, risking skin and eye injuries from heat and ultraviolet radiation. Prevent arc burn by keeping a tight arc and using proper welding techniques. Always ensure … Read more

A welding arc is an electric discharge between the cathode and anode. It forms through thermionic emission and ionizes gases. The arc voltage decreases with distance from the electrode tip. In gas metal arc welding (GMAW), the electrode melts continuously. Understanding arc physics and its heating processes is crucial for high-quality welds. Key principles include … Read more

To perform a basic electric arc weld, follow these steps: 1. Strike the arc to generate heat between the electrode and the workpiece. 2. Move the arc to form a strong weld bead. 3. Monitor the weld bead for uniformity. 4. Clean the weld area between passes. Always prioritize safety by wearing protective gear and … Read more
