Welding technology

Compact, robust welder for the toughest

conditions ENERGY-saving and cost-efficient arc welding technology was the focal point of EWM’s appearance at Schweissen & Schneiden 2013. With its BlueEvolution sustainability initiative, Germany’s largest manu- facturer and one of the leading suppliers worldwide in this field allows welding to be both environmentally friendly and economical across the whole product range. This is also true of one of the company’s trade fair highlights: the new “Pico 350 cel puls” is very energy efficient due to its standby function. But most importantly, the MMA inverter power source is extremely sturdy and exceptionally powerful, and can also be used for MIG/MAG CC and CV welding

as well as TIG lift arc welding. The Pico 350 cel puls can be used in temperatures of -25 to +40 degrees and in extremely tough conditions due to its specially constructed base. It is also impervious to dirt and water. This makes it particularly

EWM’s “Pico 350 cel puls” is an MMA welding machine which can also be used for MIG/MAG welding

generator compatibility, operation on extension cables up to 200m long and VRD functionality allow the Pico 350 to be deployed flexibly worldwide.

suitable for offshore environments and for pipeline, steel and bridge construction. The new welding machine’s cellulose electrodes also make it up to 100 per cent safe for vertical-down welding. It also masters vertical-up welds thanks to the new PF pulse function. Complete

HF welding simplified for diverse API product manufacturer

HF welding variability is reduced and repeatability is achieved regardless of operator know-how or shift-to-shift operations. The dual welding option offers the manufacturer many product options with the flexibility of using two welding processes, induction or contact, on one welding system. This gives the pipe producer the ability to achieve significant power savings when welding large diameter pipe with high frequency contact welding, yet still choose the induction welding process when needed. With the new equipment in place, the manufacturer can reliably produce high quality API and proprietary grade pipe to meet the growing demand of the global oil and gas industry.

To maximise up-time during product change-over, the predictive algorithm built into the HAZControl™ technology software guides operators to the initial heat settings. When a product has been tested and proven successful, the software allows operators to store and then easily recall welding recipes so

ONE of the world’s largest suppliers of ERW pipes has completed the install- ation of a new 800kW HAZControl™ technology dual (induction/contact) solid state HF welder at one of its North American facilities. Dedicated to serving the growing demand of the global oil and gas industry, the North American producer chose Thermatool to meet API standards required by its customers.

Patented Thermatool ® HAZControl™ technology 800kW dual welder

The organisation has a wide product matrix of API products ranging from 4.5" to 8.6" OD and 0.188" to 0.5" wall pipe. The manufacturer chose Thermatool’s HAZControl™ Technology Welder software for the ability to select HF weld power and frequency in ±1kW and 1kHz increments, resulting in industry leading heat input control during welding.
