ARC Welding

The scratch start method is the original technique for starting the arc in TIG welding. Welders manually scratch the electrode against the workpiece, like striking a match. This method is effective but may be difficult for beginners. It requires significant practice to use it correctly and safely. Scratch-start involves physically scratching the electrode against the … Read more

TIG welding in the 6G position involves welding a 2-inch pipe at a fixed 45-degree angle. This method demands precise electrode and filler material control. Key elements include using a heat shield and maintaining accuracy to form strong joints. Mastering this skill is crucial for various applications and passing welding tests. For successful 6G TIG … Read more

Low current in arc welding weakens the arc. This leads to uneven weld beads and low heat input. As a result, the cooling rate of the weld metal increases, raising hardness. Always adjust the current based on the welding procedure and manufacturer recommendations to achieve the best results. When a welder operates at low current, … Read more

Too low welding current in arc welding creates various problems. It leads to excessive piling up of weld metal, poor penetration, and wasted electrodes. It may also increase spatter and cause undercutting. Maintaining the correct amperage is vital for good-quality welds and avoiding poor fusion. Additionally, low welding currents can hinder proper penetration. Incomplete fusion … Read more

During arc welding, keep a short arc length. It should be no longer than your electrode diameter. For a 2.6mm electrode, maintain an arc length under 3mm. Do not let the electrode touch the metal. Touching can cause the electrode to stick and disrupt the welding process, affecting safety and quality. Adjust your welding settings … Read more

Arc welding is a method to join metal pieces by melting them with an electric arc. Important techniques are Shielded Metal Arc Welding (SMAW) and Gas Tungsten Arc Welding (GTAW). Programs like Napa Valley College’s Welding Technology Certificate offer safety and OSHA training. These help students prepare for Entry Level Welding jobs and Los Angeles … Read more

Toxic arc welding of galvanized steel produces dangerous fumes that mainly include zinc oxide and lead oxide. Breathing in these particles poses serious health risks, such as respiratory problems and metal fume fever. Welders must recognize these inhalation dangers to maintain safety in the welding industry. Welder safety is paramount when working with galvanized steel. … Read more

To achieve effective arc welding, hold the electrode 3mm above the workpiece. This distance ensures a stable arc. If the arc shortens, adjust the voltage to prevent it from sticking. Maintaining proper electrode distance and voltage control are essential tips for successful welding techniques and best practices. Next, select the right electrode for the material. … Read more

To arc weld, hold the electrode holder at a 90-degree angle to the metal surface. Quickly strike the electrode on the surface and pull it back 1/8 inch to start the arc. Once the arc is established, begin welding. Always prioritize safety by wearing protective gear and using the right technique and equipment. Another common … Read more
