• Stainless Steel vs Aluminum

    The question of Stainless steel vs Aluminum often arises when considering components for a number of applications. Fatigue Strength and Life –* Stainless steel* has 5-10 times the fatigue strength (resistance to bending & vibration) of aluminum pipe. The fatigue strength of stainless steel is 25-75,000 psi, compared to aluminum...


  • Flux-cored Arc Welding Shielding Gas

    In *Flux-cored arc welding, shielding gas *may be used as it generally produces welds of better and more consistent mechanical properties, with fewer weld defects than either the SMAW or GMAW processes. Shielding gas equipment for flux-cored arc welding consists of a gas supply hose, a gas regulator, control valves,...


  • Flux-cored Arc Welding Cables

    Flux-cored Arc Welding Cables In flux-cored arc welding, cables and connectors are used to connect the power source to the welding gun and to the work. These cables are normally made of copper. The cable consists of hundreds of wires that are enclosed in an insulated casing of natural or...


  • Welding Helmets, Shields, Masks

    Welding Helmets, Shields and Masks Below are some questions that are often asked regarding the choice of a welding helmet, shield or mask:  What shade lens should I use for a particular type of welding? All properly designed quality welding lenses, have a screen that filters out 100 percent of...


  • TIG Welding Aluminum with Alternating Current

    TIG Welding Aluminum with Alternating current Characteristics of TIG Welding Aluminum **with Alternating Current (AC) **Process The welding of aluminum by the gas tungsten-arc welding process using alternating current produces an oxide cleaning action. Argon shielding gas is used. Better results are obtained when welding aluminum with alternating current by using...
