This is useful guide about underwater welding. Read on..
Underwater welding is a high paying, much in demand, lucrative and rewarding profession. Underwater welding also takes a combination of skills. If you are wondering how to get started in this great career, the American Welding Society makes recommendations at their web site to encourage young people […]
A brief listing of advantages provided by pulsed MIG welding (GMAW-P) usually encourages welding technicians to see if this technology may be appropriate for their application:
All position welding with spray-like transfer
Travel speeds increase up to 35% over short circuit transfer
Ability to fine tune arc wave form
Significantly reduced spatter compared to short […]
Resistance welding is one of the oldest of the electric welding processes in use by industry today. The weld is made by a combination of heat, pressure and time. As the name resistance welding implies, it is the resistance of the material to welded, to current flow that causes a localized heating in the part.
The […]

Q: I have gas flow from the gun, but not a clean weld. How can I solve this?
A: Porosity and black welds indicate poor gas coverage or contamination. To ensure good coverage, check for: proper gas flow (CFH), leaks in the […]
Q: What are the advantages of MIG welding?
A: It’s easy to learn how to MIG weld - with a little practice, even a first-time user can achieve a good-looking weld
MIG welding is a much faster process than Stick welding
The operating cost of MIG welding is lower than Stick welding because of the […]

Q: I’ve heard that inverters let me adjust the arc to stay in the electrode negative mode for up to 90% of the AC cycle. Can this really improve my travel speed?
A: Absolutely. You can increase travel speed, get better penetration or both […]

Eye injuries account for one-quarter of all welding injuries, making them by far the most common injury for welders, according to research from the Liberty Mutual Research Institute for Safety. Those most at risk for welding-related eye injuries are workers in industries that produce industrial and commercial […]
Q: What can I do to avoid electrical shocks?
A: Wet working conditions must be avoided, because water is an excellent conductor and electricity will always follow the path of least resistance. Even a person’s perspiration can lower the body’s resistance to electrical shock. Poor connections and bare spots on cables further increase the possibility […]
Selecting a Welder for the Farm or Ranch The weather finally clears, and Wisconsin dairy farmer Al Hoffmann has 385 acres of haylage to cut and store when the chopper blower band for the silo snaps in half. Part of the 3/16 in. steel band has worn paper thin and snapped, and on this Saturday, […]
Frequency, or Hz, is the number of times the AC TIG arc switches between electrode negative and electrode positive in one second. Some products inverter-based TIG power source permits adjusting output frequency from 20 to 250 Hz. Conventional TIG machines have a frequency fixed to that of the 60 Hz primary power.
Increasing the frequency narrows the […]
Welders use welding helmet when performing various type of welding process to protect their eyes, neck, faces from ultraviolet light, sparks, and flash burn. Welding helmet most commonly used for arc welding processes to prevent retina burn and arc eye. Arc eye is inflamed cornea, which is a very painful condition, and retina burn can […]
Welders always use welding helmet when they weld, so welding helmet is number one accessories for welders. Welders can’t weld without protective eye shield. But when welders looking for next helmet, what kind of question usually appears? Below are reviews of frequently asked question.
Q: What is the correct lens shade to use in my welding […]
Welding helmet are the without a doubt the single most valuable item a welder has to protect himself.
Welding helmets have been around for a long time and the technology has steadily improved. They are much more user friendly and offer far more protection.
Still, there are a lot of misconceptions about how a welding helmet actually […]
As a professional welder, you must concern with your safety that is the first thing to remember. You are wearing a welding helmet as your precautions, but what type of helmet do you use? Wearing the right product can greatly affect your eye, neck, and ear safety. Welders are familiar with an arc flash exposure […]
Few parameters to remember when you choose welding helmet are durability and safety. That’s the most important thing to consider. Additional thing to remember is: it must fit to your head, and you feel comfortable when you use it. If you do not feel comfortable when you use it, it will affect to your final […]
