Resistance welding joins metals using pressure and electrical current, often without filler material. In contrast, arc welding employs an electric arc to generate intense heat, melting metal and usually using filler material. Each welding technique has distinct applications and benefits, making them suitable for different metal joining tasks. In contrast, arc welding utilizes an electric … Read more

Shielded Metal Arc Welding (SMAW) is a versatile arc-welding process. It mainly welds ferrous metals, like low-carbon and mild steel, and nonferrous metals, including stainless steel. SMAW is economical, portable, and robust for industrial applications. It enhances mechanical properties and has extensive research support, with thousands of publications and citations. However, sustainability assessment in research … Read more

Raised arc stud welding is a quick method that attaches metal studs to base metals. It works with materials that are 2 mm thick or more. Typical stud diameters are 3 to 25 mm. The process runs between 100 and 1,500 milliseconds. This technique efficiently welds materials like mild and stainless steel. Suitable tools enhance … Read more

Rapid Arc Welding (RAW) is a cutting-edge method for installing refractory anchors in high-temperature vessels. SILICON developed this technique to boost efficiency and decrease welding time. RAW uses SpeedBolt for reliable installations, making it a market leader in refractory anchor solutions through innovation and computer-controlled welding.

Arc welding uses more power than laser welding. It needs a high current and voltage to create an electric arc, which keeps the weld pool stable. Laser welding, on the other hand, requires less power. It uses lower current and voltage to produce a laser beam, making it a more energy-efficient option for welding tasks. … Read more

Recommended amps for arc welding depend on electrode size. For stick welding: 1/8 inch requires 75-125 A; 5/32 inch needs 110-170 A; 3/16 inch needs 140-215 A; 7/32 inch needs 170-250 A. Use the correct amperage for the best welding results. Additionally, consider the type of electrode. E7018 electrodes function well on thicker steel and … Read more

Plasma Transferred Arc Welding (PTAW) is an advanced method for applying overlays. It effectively enhances the surface of parts, such as AA 5083 aluminium alloy. Recent investigations show improved hardness values and optimized process parameters. This technique is important for applications like hardfacing and welding advancements in modern manufacturing. The recent developments in PTAW have … Read more

For arc welding, the American National Standards Institute (ANSI) recommends shade numbers based on arc current. Use shade 12 for Gas Metal Arc Welding (GMAW) at 160-250 amps. For GMAW at 250-500 amps, use shade 14. For Gas Tungsten Arc Welding (GTAW), shades range from 10 to 12, depending on the current. Using the correct … Read more

Red arc welding electrodes have different classifications, such as E7018, which is suitable for mild steel and low alloy steel. The “E” stands for electrode, and the numbers indicate strength and design. Low hydrogen electrodes (Exxx5) ensure better quality welds. Understanding these electrodes helps in choosing the right one for your welding process. For example, … Read more
