Wait... did your weld just crack HOURS after you finished? 💥

Here is exactly why that happens when you don't preheat. 👆

If you weld a thick plate of high-strength steel at room temperature, the cold metal sucks the heat out instantly. This traps carbon atoms in the lattice, creating a brittle structure. The result? Delayed cold cracking. 📉

Don’t risk your hard work. Calculate your exact preheat temperature (like the 140°C shown in the video) before you even start.

On October 6, 7, and 8, you can find us at the exhibition in Gorinchem! Our dealers , Kumoweld , and are joining forces under the name: Welderbrand. We will be joining them at their booth to make innovation truly visible.

No standard sales pitch, but real action! We will be demonstrating our CEWELD® Ultra Clean welding wire live. Using an advanced @ . camera, you can watch the welding arc directly and in crystal-clear detail on our screen. 👁️

Want to see with your own eyes how this wire ensures a cleaner welding process and better efficiency? Block the dates in your calendar!

📍 Evenementenhal Gorinchem
📌 Booth G40 (with Welderbrand)
We will share more details about the demonstrations soon.

Welding a ball bearing to structural steel? Most welders will tell you it’s impossible without cracking... and normally, they’d be right.

With the CEWELD® CroNi 29-9 S electrode, we show you how to weld even the most challenging high-carbon steels crack-free.

Why the CroNi 29-9 S is the ultimate problem solver in the workshop;
Extreme crack resistance: The electrode absorbs shrinkage stresses effortlessly.
Flawless control: A super stable weld pool with zero spatter.
Perfect for repairs: Ideal for gears, shafts, buffer layers, and unknown or dissimilar steels.
Self-peeling slag: Leaving a perfect, smooth finish.

Don't let "unweldable" steel slow you down.

Large root gap when welding? Watch your heat input and T8/5 cooling time!

When you have to execute a weld with an excessively large root gap, for example, 12 to 16 mm instead of the ideal 5 mm, the heat input rises sharply, and the cooling slows down drastically. But what does this actually mean for the strength of your weld?

In our latest blog, we dive deep into the microstructure of the metal and show you why the T8/5 cooling time is the absolute thermometer of toughness:

❄️ Cooling too fast: The metal forms an extremely hard but dangerously brittle structure, greatly increasing the risk of cold cracking.
🐢 Cooling too slow: Coarse ferrite grains form, which offer barely any resistance to crack propagation.
✅ The perfect balance: The optimal cooling time limits grain growth and allows the most desirable structure to form: acicular (needle-like) ferrite. This acts like a dense 'briar patch' that forces a crack to constantly change direction until it completely stalls.

The result? Legendary toughness, even in extreme freezing cold!.

What is aluminum really made of? And how do you weld it successfully?

Aluminum is an indispensable material in modern engineering. It is lightweight, incredibly strong (when alloyed), and offers endless possibilities. But as any professional knows: welding aluminum is a craft of its own. The stubborn oxide layer, the crucial balance between argon and helium, and selecting the perfect alloy make it a challenging material to master.

Our Technical Manager & Filler Metal Specialist, Andreas Holzner, has written an in-depth blog exploring the core essentials of aluminum metallurgy and welding.

In this blog, you will discover:
✅ The unique properties of pure aluminum vs. aluminum alloys.
✅ A clear breakdown of the EN designations (from the 1### to the 8### series) — as shown in the alloy tree below!
✅ Why AC TIG welding is essential to break through that tough oxide layer.
✅ The impact of different shielding gases (and how our CERTILAS GasGuide PRO helps you choose the perfect mix).

Whether you are an experienced welder or looking to brush up on your material science, this guide is a must-read.

Rest in peace, welding table... 🪦
We engineered a custom chisel using CEWELD E DUR SS 60 Ti (60 HRC) just to see what it could destroy. Turns out, a welding tablel doesn’t stand a chance. 💀

Sound on to hear that impact! 🔊
