Tungsten inert gas welding is one of the most common arc welding applications used in industrial manufacturing. TIG is a precision welding method that is capable of producing quality welds where detail is key. TIG is also popular since it can be used to weld almost all alloys and metals. One drawback to TIG is it is a slow and complex process, however, automation with welding robots eases the application of this welding method.

TIG can be automated by integrating an arc welding robot with a power supply, welding torch, and safety equipment. The FANUC Arcmate 120ic is ideal for TIG welding automation. Automating TIG welding with robots not only eases the welding process, it also provides a number of benefits.

  • • Control of Welding Variables - There are several variables that must be controlled during TIG welding in order to produce quality welds. The amount of heat, torch speed, amperage, voltage, and arc depth are some of those variables. Automating TIG with robots allows for all welding variables to be programmed and remain consistent throughout the welding cycle. The Motoman MA1400 is able to maintain the same speed, heat, and proximity while welding, resulting in uniform and precise welds. With manual welding it is impossible for welders to be able to control welding variables consistently, no matter how skilled the welder may be.

  • • Increased Productivity - While TIG is known as a slower welding process, automating it with robots optimizes cycle times to significantly improve productivity. The ABB IRB 1600 is programmed to move from weld to weld with no hesitation and can operate twenty-four-hours a day. The efficiency of the FANUC M710ic/20L operation allows for more parts to be welded. Automating TIG has shown to increase productivity rates between 100% to 300%.

  • • Resolves Welder Shortages - The welder shortage that is currently ongoing is only expected to worsen, which is one of the reasons manufacturers are automating welding applications. The welder shortage is especially apparent with TIG welding, as this is a highly complex method that takes great skill and experience. Automating TIG with welding robots provides the skillset needed for this highly complicated application without wasting time searching for welders or training. By simply programming the FANUC Arcmate 100ic with your application parameters you will receive the weld quality of a seasoned welder.

  • • Reduce Costs - Implementing an arc welding robot for TIG applications will help save manufacturers money in the long run. TIG welders often have high salaries since the welding method requires a high skill level that can also be rare to find. Deploying an arc welding robot will eliminate high labor costs associated with TIG. In addition, the accuracy of TIG welding robots will prevent material waste, further decreasing production costs.

  • • Improved Weld Quality - Robotic TIG welding will improve weld quality. Robots are programmed to operate in accordance with the application parameters specified for incredible accuracy and repeatability. Their precision and control prevent errors that result in defects and irregularities producing welds that are high-quality and uniform across all workpieces. Welding robots can be integrated with robotic vision systems for even greater welding accuracy. Vision integrated robots may also be able to perform their own quality control inspections, reviewing their welds before parts move further along in the manufacturing process.
