Concern ESAB welders released budget line Buddy:

• Buddy Arc 145 for manual arc welding (MMA);
• Buddy Arc 180 and Buddy Arc 200 for manual arc welding and TIG welding with tungsten electrode (TIG) with the ignition of the arc margin;
• Buddy Tig 160 for TIG welding with HF ignition of the arc (TIG HF) and MMA-welding.

The models differ in a simple control, overload protection, safe housing, designed for harsh environments, as well as efficient inverter technology-based IGBT (bipolar transistors with insulated gate).

The devices support hot-start function (Hot start), anti-sticking electrode (Anti stick), stabilization of the arc (Arc Force). You can manually welding with direct current iron, alloyed and unalloyed steel and other metals.

Buddy Arc Models 180 and 200, Buddy Tig 160 allow you to weld stainless steel and tungsten low-carbon steels with a filler material or without it (in the presence of the burner, regulator and gas cylinder).

Buddy Tig 160 - Mobile phone for professional TIG-welding. The high-frequency arc ignition (TIG HF) is carried out without touching the product tungsten electrode, which prevents the likelihood of tungsten in the seam. Chance of a two-or four-stroke mode including the burner.

Research Fellows of the Institute for the Study of Fraunhofer physical methods of measurement (Freiburg, Germany) have developed a new method of laser welding no through penetration of the welded products. In this case the laser beam does not reach the bottom surface of the metal and leaves no visible marks on it. Experts call this technology "controlled by welding with a partial penetration" (Controlled partial Penetration welding).

Fraunhofer Institute in cooperation with scientists from the Stuttgart and Dresden was a prototype, which controls the process of laser welding. To monitor the process uses an innovative thermal imaging camera, which generates up to 14,000 images per second. The system determines the depth of penetration of laser shots and controls the power and duration of its emission.

A new welding method is very promising in the automotive industry, because it requires no further processing outside seams or finishing decorative panels. In addition, the evaporation of zinc is excluded at the bottom of the joint, leading to corrosion of galvanized car bodies.

The German company Merkle began manufacturing semi-automatic welding MobiMIG 280 K. Small size and support for various welding conditions make them excellent tools for installation and service work.

Modes of the device:

• MIG / MAG (semi-automatic welding);
• TIG DC (tungsten arc welding with direct current);
• MMA (manual welding stick electrodes);
• welding flux cored wire;
• MIG-brazing;
• ColdMIG (semi-automatic welding or brazing with low heat dissipation).

Technology ColdMIG with low impact on the 20-30% of heat is used for welding sheet metal thickness of 0,6-3 mm sheet with a large gap between the two, dissimilar metals, metal products, coated, as well as for MIG-brazing. When welding wire can be used AlMg, AlSi, CrNi, and soldering - wire CuAl, CuSi.

The new model operates from 1x230 or 3x400 in V. When the input voltage of the apparatus required is automatically selected (function BiPowerPLUS).

Concern ESAB acquired from ATS ( Applied Thermal Sciences Inc, USA), the main process controller MPC (Master Process Controller), intended for use in hybrid laser-arc welding. MPC - a patented system that provides real-time control of laser equipment for arc welding in shielding gases (GMAW, MIG / MAG) welding system and moving heads. ESAB Cooperation and ATS in the development of this adaptive control system lasted for over six years.

Hybrid laser-arc welding combines the advantages of both methods. The laser beam provides deep penetration and a relatively low heat input and arc process in inert gas (GMAW) - excellent properties of welded joints and the possibility of increasing the gap between the workpieces. Hybrid welding can be performed at very high speed, with the joints obtained by narrow and deep. Often a single pass using a laser-arc welding is achieved the same results as in several passes with conventional fusion welding.

With the acquisition of MPC concern ESAB was able to use their equipment Hybrio for laser-arc welding of thicker materials and wider gaps between products. The company will continue to develop this area further.
