Whether structural steel welding is taking place in an indoor shop setting or outdoors in the field is a factor that either introduces or eliminates a host of elements, including wind, the enemy of shielding gas and the welding processes that rely on it. Here are some insights to help you choose the right structural steel fabrication process for a field application or for shop welding.
With its low melting point, the presence of an oxide layer on its surface, prone to burn-through with a difficult-to-control weld pool, aluminum can be somewhat tricky. Here are some insights that will provide you with the best course of action to take for making a repair.
Not every welding application requires the benefits that higher priced seamless wires provide. But when moisture must be controlled to help minimize the risk of hydrogen-induced cracking in demanding high-strength applications – and with it, costly repairs or potentially catastrophic weld failures – seamless welds are the ideal solution for the job.
The comprehensive stainless steel filler metals line from Hobart Brothers has expanded to include stick electrodes and metal-cored wires by adding options in solid wire and flux-cored wire.
Unlike the red-tipped thoriated tungsten electrode that contains two percent thoria, blue-tipped MultiStrike tungsten electrodes from Huntingdon Fusion Techniques HFT contain a mix of non-radioactive rare earth elements, eliminating the risk to health posed by thoriated tungsten electrodes.
The properties of stainless steel offer corrosion resistance, toughness and strength, a good appearance and longer useful life. But there are some challenges when welding stainless steel. Consider these tips and best practices, including proper filler metal selection, to get the most from stainless steel welding applications.
Ideal for demanding applications in pipe, pressure vessel and tank, railcar manufacturing and heavy construction/mining, this process offers great benefits in its simplest form of single wire welding, plus more in twin wire, tandem wire and multi-wire SAW configurations.
The 2016 edition of FABTECH is on track to be one of the largest metal fabrication events ever at the Las Vegas Convention Center in Las Vegas from November 16-18. This special sneak peek provides technical reviews of some of the equipment, power sources, positioners, systems and accessories that will be exhibited in the Welding Pavilion to help you get a head start on navigating the show floor and managing your time while you’re there.
Filler metal solutions from Hobart Brothers improve productivity, quality and cost savings in metal fabrication and manufacturing applications.
Nothing pushes the limits of machine performance – or weld strength – like offshore powerboat racing. To meet its demands of higher strength, corrosion resistance, ease of welding and low hot cracking sensitivity, this powerboat drive builder uses an advanced aluminum filler metal that significantly strengthens weld joints after post-weld heat treatment and machining, without affecting the integrity of the base metals.
