Lorch Schweißtechnik GmbH is a clear master of speed, using advanced welding processes to increase welding speed and optimize arc performance for specific applications.

The company manufactures arc welding systems for industrial applications, demanding metal processing, and automation of robotics and collaborative robot systems.

With next-generation inverter power technology and digital control, Lorch provides cutting-edge performance at faster welding speeds while producing excellent metallurgical weldments.

Lorch's latest generation S series and MicorMIG platform using "speed" technology are more efficient, consume less power, and weld faster. David Wilton, managing director of Lorch South Pacific, explained that speed can translate into productivity and reduce operating costs. In order to achieve this goal, the welding process needs to be optimized, which starts with the digital welding machine.

"The Lorch platform is a 100% digital system that enables advanced welding processes that are completely driven and controlled by software," Wilton said. "This is the difference between modern Industry 4.0 welding machines-it is digital, and the processing speed is very fast, capable of advanced welding processes."

Wilton said that the digital platform represents the development of the welding process and has been optimized to a new level.

"When it is controlled by software, we can manipulate the welding arc to do different things," he said.

"We are doing this to increase productivity, and overall, the main goal is to complete faster, with superior quality and superior weld integrity, which means that the welding strength is actually optimized in this way.

"Last but not least, it actually makes the operator's task easier. Advanced operations-you can make welding simpler and easier," Wilton said.

The Lorch Speed ​​process is an advanced process suitable for solid, flux-cored and metal flux-cored welding applications. Wilton and "Manufacturer Monthly" shared how they comprehensively improved all aspects-speed, quality and ultimately cost savings.

SpeedPulse XT relies on its advanced waveform control technology to quickly master pulse welding. Pulse welding has been around for a long time. It is ideal for welding thinner materials, but it has a basic flaw in that the process is slower than the traditional transfer mode and generates a lot of heat in the torch.

“Now SpeedPulse XT is overcoming this problem, because what is happening now is not a small droplet produced per pulse, but multiple connected droplets, each pulse accompanied by a flow of molten metal,” Wilton said. "Gone are the days of slow single-drop pulse welding. Today, SpeedPulse XT relies on its patented technology to accelerate the entire welding process by depositing significantly more volume per pulse."

Lorch SpeedPulse XT is the forefront of pulsed MIG (GMAWP) welding technology, which provides ultra-fast welding speed, reduced deformation and extremely low, insignificant spatter levels, reducing any post-weld cleaning time.

"Whenever we have a pulse, all it does is deposit more molten material into the welding pool. When you put more molten material into the welding pool, your physical movement speed will be faster, Produces a weld size comparable to the traditional single pulse system. This really speeds up the pulse welding process. Therefore, with SpeedPulse XT, your speed will be 48% faster than traditional pulse welding," Wilton said. "This is also a proprietary proprietary IP owned by Lorch, and this software can achieve this."

SpeedArc (MicorMIG) and SpeedArc XT (S series)

SpeedArc is a better and more advanced process than standard MIG (GMAW) or flux-cored welding (FCAW) because the user can manipulate the arc to obtain a more concentrated and concentrated arc. This advanced process can penetrate deeper, provide better welded joints, and thus provide better structural integrity.

"Through the rapid arc process, we can manipulate and control the arc so that the arc is really focused," Wilton said. "Compared with the ordinary MIG-MAG machine, it has a higher arc pressure and a more concentrated wire end energy, which can penetrate deeper into the steel.

"Using the Speed ​​Arc process, the welding speed is 30% faster than the standard process using the same wire and gas."

Wilton explained to the steel structure manufacturer that one of the biggest costs in welding is labor time.

"If we can speed up the process and the welder can lay down more kilograms per hour and achieve a higher deposition rate, then the work will be completed faster and the cost will be reduced," he said.

Practical applications that were usually done by TIG welding in the past can now be welded using the MIG-MAG process, which is 7 times faster and has the breakthrough features of the new and improved TwinPuls XT. The result is comparable to TIG.

"What we produce through digital control is a TIG-like appearance," Wilton said. "The scaly appearance is usually the visual appearance you get using the TIG process, which is related to the best quality."

"Using advanced digital machines, we were able to reproduce a TIG-like appearance, but at a 7 times faster speed, and provide operators with a simpler MIG (GMAWP) process while still looking perfect."

Using MIG for vertical upward welding always requires a lot of experience, skills and stable hands to perform traditional "Christmas tree" welding, but the acceleration option makes vertical upward welding easy without weaving.

"As you can see in the picture, this welding is done in a vertical position, so the welder is welding directly upwards. This is another remarkable process, and now it becomes easier by using more advanced digital welding technology. Produce consistent, high-quality results," Wilton said.

Metal core wires can also be accelerated, and vertical seams can now also be produced quickly and easily. It is no longer necessary to replace the welding wire with rutile flux-cored welding wire, thus saving time and money.
