Welding  Manufacturers, Traders, Suppliers

A wide range of special products
The production of cable drums and bucket wheel shafts is just an example for the complexity of products we are able to supply for different heavy industry applications.
From experience we know where innovative solutions have to be placed in order to result in substantial improvement. We rely on well-engineered technologies, the necessary engineering know-how and develop of long term successful solutions in close cooperation with our customers. We assist our customers to help them concentrate on their core business and thus to create an important scope for their own technological development.
The aim is we never lose sight of the economic efficiency of a solution. The proven cost-benefit ratio assures you that you can rely on the well-proven GW | value in the future.
Our focus regarding NE products are high-end products for the following industries: Aluminum, shipbuilding, pulp & paper, pumps, special machine building, gear box producers, cement, copper, and a lot more.

We are specialized in welding components for rail vehicles and have been certified by the Swiss Welding Society (SVS) according to EN ISO 15085-2 CL1.
The combination of high quality manufacturing and welding offers our customers the following advantages:

• a complete production of your components from one source
• only one contact person
• shorter throughput times
• flexible deadlines
• cost-efficient manufacture
• short communication channels

Even before the first mechanical processing, the optimum weld seam preparation is discussed with the welder and carried out accordingly. The mechanic plans with the Sc

STC - This stands for the Lorch Welding Technology Center in your region. Only a few welding dealers receive this honour. The prerequisite for this is a high quality standard in terms of advice, service and customer service.
We offer you a full service Not only sales but also repairs and warranty repairs are daily business for us.
For this purpose we select the suitable welding consumables or welding processes for you and are pleased to advise you. In case of a machine bottleneck you can also rent various machines and accessories from us.

The main emphasis for orders of the company IMH is in the production, delivery and assembly of piping for, for example, waste water systems, paint finishing systems, biogas plant in the car and general industries.
Furthermore, systems or their components are produced by us in Burgtonna and mounted locally.
In doing so, we always have a new challenge with which we have to prove ourselves at home or abroad!
Through the challenges which arise from anew each time, a very good team has developed in Burgtonna!

Ultra-accurate welding – time and again
Our welding robot really gets to the point – the welding point. Short set-up times mean we can easily process small batches and react to our customers’ needs quickly and flexibly. We program our systems to store and recall precise welding points, slashing set-up times and costs and ensuring we meet every deadline. What’s more, this allows us to minimise processing time and boost delivery capacity. Our welding robot works extremely cleanly, reducing the need for final touches afterwards. Unmatched accuracy and repeatability mean part after part is identical – in fact, you could even say our welding robot is fussy.

Not only banks but also security firms, embassies and increasingly even public authorities have a growing need to protect their premises.

Forklift hydraulic pump a critical component of the hydraulic system, responsible for converting mechanical energy (from the engine or electric motor) into hydraulic energy by generating pressurized fluid flow. This pressurized fluid powers hydraulic cylinders and motors, enabling lifting, tilting, and steering operations in forklifts.

Applied to forklift manufacturing

Our welding machines are compact, portable, and user-friendly. The weld beam is aesthetically pleasing and requires no grinding after welding. Besides, we can provide various customized services. For example, we can connect the welding head to the robotic arm, enabling automated welding of complex components.

Laser welding outperforms traditional methods with key advantages: High energy density enables ultra-precise, narrow welds with minimal heat input, drastically reducing the heat-affected zone (HAZ) and material distortion—ideal for delicate parts. It operates at significantly faster speeds, enhancing productivity in mass production. It excels at joining dissimilar metals or thin materials that traditional techniques (e.g., arc welding) often struggle with. Additionally, its controlled heat application minimizes defects, yielding stronger, more consistent welds, and it integrates seamlessly with automation for precision in industries like automotive and aerospace.

Weldable materials: carbon steel plates, stainless steel plates, aluminum plates, etc.Max welding thickness: 1mm to 5mm.
