ARC Welding

Electric arc welding is a metal joining process. It generates heat through an electric arc between an electrode and metal pieces. This heat melts the materials at contact points, forming a strong bond. Safety precautions are essential. Different types of arc welding offer various applications and advantages. For those interested in mastering Electric Arc Welding, … Read more

Double submerged arc welding (DSAW) is a welding process that primarily serves the oil and gas industry. It produces large-diameter steel pipelines by welding the inside and outside surfaces at the same time. DSAW pipes come in both straight and spiral forms, providing strong and durable weld joints for diverse applications. Applications of DSAW are … Read more

To select the right arc welding rod, consider the metal thickness. For metals up to 1/4” (6.35 mm), use a 1/8” (3.2 mm) rod. If the metal is 2mm to 6mm thick, choose a rod that is one size thinner. Common sizes are 1/16”, 3/32”, and 1/8”. This selection ensures perfect welding results with a … Read more

An arc gap in welding is the distance between two conductors during electrical discharge. There are two types: Alternating Current (AC) and Direct Current (DC) arc gaps. AC gaps typically occur when conductors are 2-4mm apart after contact. A stable arc forms at this distance, allowing for effective welding. When the arc gap is too … Read more

Most ArcOne welding helmets are solar-powered, reducing battery replacement needs. For models with replaceable batteries, use standard AA batteries (1.5V). Always check the user manual for your model’s specific voltage requirements and safety warnings about battery replacement to ensure proper use and safety. First, turn off the helmet and remove it from your head. Then, … Read more

Each bottle weighs 0.5 oz and contains an advanced formula. For personalized care, consult an eye care professional for treatments and infection prevention options. These eye drops contain soothing and healing ingredients … Read more

An arc crater in welding is a weak point at the end of a weld. It occurs when not enough filler metal is used and the weld puddle isn’t properly cooled. This defect can lead to cracks in the metal. Proper management of the welding process can help prevent these issues and improve the strength … Read more

To determine the correct amperage for stick welding, use a chart that links electrode size and metal thickness. Usually, set 1 amp per 0.001 inches of thickness. For thin metals, choose lower amperage; for thicker metals, select higher amperage. This method helps novice and experienced welders select the right settings for their application. Keep in … Read more

Recommended amperages for stick welding depend on electrode type and diameter. For a 1/8” electrode, use 75-125 amps. A 5/32” electrode requires 110-170 amps. A 3/16” electrode needs 140-215 amps. Refer to this amperage chart for shielded metal arc welding to achieve the best results in your projects. For example, a 1/8-inch electrode generally requires … Read more

To optimize arc welding amperage, use lower settings for thin metals and higher for thick metals. For example, 6013 electrodes need 40-60 amps for 2.0mm and 130-170 amps for 4.0mm. Start with lower amperage for vertical up welding and higher for flat fillet welds to achieve proper penetration. Welder type also influences amp settings. For … Read more
