Welding Costs – WELDING ANSWERS

This article challenges the common assumption that reducing amperage and electrode diameter lessens welding distortion. It explains that lowering amperage also decreases deposition rate, forcing slower travel speeds which can negate heat input reduction or even increase total heat input due to the inverse relationship between travel speed and heat input. The surprising solution often involves increasing amperage and travel speed to reduce overall heat input, though the most significant factor in minimizing distortion remains maintaining the smallest possible weld size.

This post provides answers to frequently asked questions regarding the "280 Prequalified Welding Procedures for Stainless Steel" product. It addresses common inquiries from customers about the digital format, permissible uses for CWIs, distinctions between qualified and prequalified procedures, and the rationale behind the product's affordability. Additionally, it clarifies compliance with AWS D1.6, modification flexibility, and how included guides facilitate proper use and customization of these welding procedures.

Weld design, encompassing joint selection, sizing, and filler metals, is inherently linked to the preceding element design stage, where a structure's overall components are conceptualized. Decisions made during element design—like considering loads, materials, geometry, and manufacturing constraints—profoundly influence the subsequent weld design by dictating load transfer, material compatibility, and weld accessibility. A disconnect often exists between design engineers, skilled in element design, and fabrication staff, leading to practical challenges in implementing welded connections. Bridging this gap through collaboration is crucial for creating safe, functional, and cost-effective structures.

Skilled welders are a valuable asset—but too often, their time is wasted on non-welding tasks. In this post, we break down 8 proven ways to increase welder efficiency and get more value from your team. From smarter fixturing and better equipment maintenance to choosing the right welding process and consumables, these practical tips will help your shop boost productivity without burning out your welders. If you’re serious about improving throughput and lowering costs, this article is a must-read.

Rework in welding is a massive productivity killer—tripling labor, wasting material, and slowing down production. While there are many causes, three simple fixes can drastically reduce rework: stop overwelding, use properly qualified welding procedures, and maintain your equipment. In this post, we dive into how these small changes yield big results—lowering costs, improving quality, and increasing efficiency across the shop. If you're tired of grinding out the same welds twice, this is the post for you.

Want to boost welding productivity? Increasing your deposition rate is one of the most effective ways—but only if done right. This post explains the difference between melt-off and deposition rate, how higher deposition leads to faster travel speeds (and real time savings), and the common mistakes that sabotage these gains. Learn how to avoid costly errors, why simply turning up the amps isn’t enough, and how training and proper welding procedures can unlock major efficiency improvements in your shop.

While cracks are often considered the "worst" weld defect, the most dangerous ones are those that go undetected and are put into service. Many common discontinuities like lack of fusion, internal porosity, or even small surface cracks can be missed if quality control standards are inadequate or if inspections are timed improperly. For example, hydrogen-induced cracking can appear up to 48 hours after welding, and incorrect shielding gas for stainless steel, though visually appealing, can lead to costly premature corrosion or sensitization in service. Effective quality control, including qualified procedures, trained welders, and appropriate inspection timing and methods, is essential to prevent these hidden, catastrophic failures.

In many fabrication shops, welders are often left to determine weld sizes due to a lack of clear specifications from design engineers or customers. This common practice frequently leads to overwelding, where fillet welds are significantly larger than necessary, wasting material, gas, and labor. Beyond the increased cost, overwelding also introduces quality issues like distortion and slag inclusions, paradoxically causing more failures than undersized welds. While structural welding codes provide minimum weld sizes to ensure adequate heat input, these often appear "too small" to welders, leading them to apply excessive weldment.
