In MIG/MAG welding, the length of wire stick-out will directly affect the welding quality. 

Here, we will briefly introduce the problems related to wire stick-out and give some suggestions on how to solve the problems.

12Cr1MoVG is a pearlitic low-alloy heat-resistant steel. Because its chromium content is relatively high, this type of steel has good thermal strength and fatigue resistance at temperatures between 500℃ and 550℃. The chemical composition and mechanical properties of 12Cr1MoVG steel are shown in Tables 1 and 2 below.

In stainless steel fabrication, weld quality is not just about mechanical strength during welding. It is also about chemical integrity after welding. Recently, Sichuan Morrow Welding Development Co., Ltd. (Morrow Welding) released a technical guide about "Heat Tint" in stainless steel welding. This guide helps users get better stainless steel corrosion resistance. It uses two methods together: "high-precision welding equipment" and "scientific post-treatment."

 In welding quality management, welding porosity is a big problem. People call welding porosity the "hidden killer." Welding porosity makes up 15-20% of all welding defects. This problem makes structures weak and shortens their life. To stop welding porosity, you need more than just cleaning. You need a good power source that can control the arc very well to prevent welding porosity.

In heavy industries like pressure vessels, large steel structures, and shipbuilding, welding stress is very important. It affects how long parts last and how safe they are. Welding makes heat uneven, and this causes residual stress. This stress can make parts bend or even crack. Morrow Welding is an expert in industrial welding power sources. We do not only care about welding speed. We also use advanced power control technology. We help customers solve problems caused by welding stress. Our focus is on Welding Stress Relief and Source Control Solutions.

In sectors where structural integrity is very important, like shipbuilding and large-scale steel construction, welding speed and quality define productivity. The submerged arc welding machine is key here. It is known for deep penetration and high deposition rates, and has long been the backbone of heavy industry.

Today, Morrow Welding is improving this essential process. We add advanced digital control and Hot-Wire technology to our machines. So, our submerged arc welding machine solutions now deliver more speed, precision, and energy efficiency for tough jobs.

Shipbuilding is a heavy industry. It has very strict needs for welding technology. Weld quality directly affects a ship's strength, corrosion resistance, and service life. TIG welding is one important process. TIG welding has become a key precision technique in modern shipbuilding because of its special benefits. This article looks at the important role of TIG welding. It starts with the technical basics and then looks at where it is used.

SMAW, widely called stick welding, is a classic manual arc welding process using flux-coated consumable electrodes. An AC or DC arc melts the electrode tip and base metal to form a weld pool. The flux vaporizes into shielding gas, blocks air contaminants, forms slag for weld protection, stabilizes the arc, and enhances weld properties via deoxidation and alloying. Post-cooling, slag is chipped off to expose the weld. SMAW boasts simple, portable equipment, broad metal compatibility, all-position welding ability, and strong outdoor adaptability. Yet it has drawbacks like low productivity, high skill demands, and slag inclusion risks, making it ideal for construction, pipeline work, and maintenance tasks.

Morrow Welding Development Co., Ltd. (Morrow Welding), a trusted global supplier of welding power sources for important industries like shipbuilding, oil & gas, and metallurgy, has released a new analysis. This analysis shows how the precise low-current stability of its top welders is changing high-quality, thin-material fabrication. Low current welding is key here.
