Kemppi's advanced welding processes: TIG and stick welding (MMA)

In TIG welding, process development has mainly focused on modifying the current modes in different situations. In practice, this means variations of pulse and AC welding, as well as ignition or tack welding. In the case of pulse welding, the welding machine user has numerous choices, as the adjustment possibilities for these process variations are highly versatile.

Introducing the X3 FastMig

MIG Welding Highlight

Complete high-quality welds in any work environment. With easy-to-use controls and a durable design, the X3 FastMig is a brilliantly simple MIG/MAG welder that is perfect for heavy industrial welding. With 420–450 amps of power at a 60% duty cycle, the X3 is brutally effective without compromising quality. It's extremely powerful, but it's also precise enough for welds that just need to be done quickly.

Some metals, like aluminum, have a naturally occurring, tough surface oxide layer. That surface oxide layer must be removed to enable successful welding. In the case of aluminum alloys, the surface oxide layer has a significantly higher melting temperature (approximately 2000°C) than the melting temperature of the aluminum base material (660°C).

Making weld cleaning easy and cost-efficient

Making weld cleaning easy and cost-efficient

Blog

Welding is all around us. It binds together the metals to build structures essential to our everyday lives. However, beyond the visible sparks and strong connections, there's an aspect often underestimated: weld cleaning. Especially with stainless steels, proper weld cleaning not only improves the aesthetic appearance of the weld but also ensures its strength, durability, and overall quality.

Energy-efficiency in welding 🔋👨‍🏭

With Kemppi’s energy-efficient welding machines, advanced welding processes, and WeldEye welding management software, you can reduce electricity consumption.

Technologies like Reduced Gap Technology (RGT), WiseSteel, and WiseRoot+ reduce rework, filler material use, and arc time, enabling fewer weld passes, more stable processes, and lower energy and material consumption.

Benefits of Reduced Gap Technology:
• Less weld passes needed
• 38% saving on arc time
• 25% less filler material

Benefits of WiseSteel:
• 30% reduced labor costs
• 30% reduction in grinding costs compared to standard MIG Welding
• 25% savings in straightening costs

Benefits of WiseRoot+:
• Up to 80% more productivity
• Up to 50% lower labor costs per welded meter
• Up to 50% savings in filler material through reduced groove angles

Kemppi’s welding machines are designed for high efficiency and precise power control to reduce unnecessary energy loss. System-level efficiency is just as important, which is why selecting the correct welding cable size and length helps minimize resistance and power loss during welding.

Tie it all together by using WeldEye for data-driven monitoring. By tracking energy use, material consumption, and production performance, WeldEye helps you identify saving opportunities and achieve measurable reductions in energy use, waste, and emissions, especially during the use phase, where impact is greatest.
