T his is a question that is often asked. The short and quick answer is: they are all the same. However, to understand why that is let’s take a quick look at the three elements that determine the strength of a weld: Weld length Weld size Weld (filler) …
7 Reasons to Consider Stick Welding Over Other Processes
Stick welding has many significant advantages over mig welding (GMAW), flux-cored welding (FCAW), tig welding (GTAW) and subarc (SAW). Below are a few of these advantages. Low equipment cost – SMAW requires very simple equipment that is relatively inexpensive compared to even the most basic mig welders.

2015年9月7日 · A lthough most people may believe that stick welding is antiquated and a bone-headed choice for a welding process, this is simply not true. It is true that in production welding, especially in a controlled environment like a fabrication shop, the use of stick welding is typically a big mistake due to its low efficiency, extremely […]

Gas Metal Arc Welding (GMAW) and Submerged Arc Welding (SAW) can have 98-99% deposition efficiency. However, the question is a bit more complicated since when we talk about efficiency we don’t just care about deposition efficiency (how much of the electrode becomes weld metal). What we care about […]
3 Effective Ways to Reduce Welding Rework
2024年11月7日 · Use properly developed and qualified welding procedures. When welding procedures are developed and qualified properly they provide reasonable assurance that a good weld will be deposited. Of course, welder skill is still essential. The best welding procedure can be worthless if the welder does not possess the skills to deposit a quality weld.

Tig welding can produce beautiful looking welds, and more importantly, x-ray quality deposits on some of the most critical welding applications. For the beginner it may be a very intimidating process. Selecting the right tungsten (type and size), cup size, and shielding gas and gas flow can be a daunting task. Below is a quick […]
What Filler Metal Should be Used to Weld Carbon Steel
2019年3月27日 · It is not uncommon to find fabricating shops that are welding a variety of metals including carbon steel, stainless steel, aluminum and nickel alloys. In many cases some of these materials need to be welded to other types. Once very common situation, especially in automotive applications is welding carbon steel to stainless. One of the […]
Control Your Shielding Gas Usage - WELDING ANSWERS
Hello, sorry that the wording isn’t clear. So let me use a hypothetical example to explain…If you purchased 10,000 pounds of wire in a 12-month period and your average melt-off rate is 7 pounds per hour (average of all welding stations) then your total welding hours are (10,000 lb) / (7 lb/hr) = 1,428.57 hours.
Welder Certification - WELDING ANSWERS
Their customers requires that anyone welding on their frames be a certified welder. When ABC asked their customer which certification was needed the answer was “we don’t know, we only require that they be certified welders.” In this case if the welders have certifications on TIG or SMAW it would satisfy the customer’s requirements.
How to Weld Cast Iron - WELDING ANSWERS
Cast iron is not impossible to weld, although many that attempt to do so end up with cracked welds. The reason welding cast iron is a big challenge is that it contains up to 4% carbon. This is an insane amount, considering that any material with a carbon content above 0.30% is already considered “medium […]
