A boom in the defence industry: What does this mean for the welding and cutting sector?

USE: What are the considerations to take into account when welding and cutting armour steels?

MR: In principle, our DIFENDER grades involve alloyed tempered steels that are easy to work in cutting, welding, bending or mechanical processing. However, some knowledge of processing should be a prerequisite. When cutting, pay particular attention to the correct preheating/reheating procedures. Depending on the individual grade, and in case of harder and higher alloys, the cutting process should be as "cold" as possible, for example using water jet systems, in order to keep heat input as low as possible. Staff processing these steels should also have the appropriate knowledge or should undergo appropriate training.

USE: What skills are required in welders and cutting machine operators?

MR: As operators, they should have as much experience as possible. Depending on their area of responsibility and the requirements for each type of welded part, they must also be trained separately and pass a professional examination in accordance with DIN2303, e. g. Q3. This standard must be met by companies working with armour materials.

USE: How and where can you train for processing the steels in question?

MR: The defining standard here is DIN2303. You must also consult with the WiWeb (Military Science Institute for Materials and Supplies) and the WTD (Military Technical Service) of the Bundeswehr. You can then undergo a qualification process. There are companies specialising in the training of welders in accordance with Q3. Relevant employees can be trained here. 

USE: Which welding and cutting methods are used predominantly?

MR: Depending on the grade and thickness of the DIFENDER sheet metal, plasma, laser or water jet cutting methods can be used for cutting. When welding, it is usually the MAG welding process which is used, which is widely employed for high-alloy steels.

USE: In which areas is the demand for safety and armour steel seeing particular growth?

MR: The increasing demand for our DIFENDER grades ranges from the civilian to the military sector: from secure limousines to armoured vans and military vehicles.

USE: Is there one basic tip you would like to pass on to armour steel processors?

MR: It is best to consult with the steel/sheet metal producer in advance, to take the appropriate processing instructions into account and to use trained staff.

USE: Thank you for talking to us!

New welding and cutting trade fair format

What other trends are there to change the world of welding and cutting? The Urban Steel Expo 2027 will answer this question. The Ultimate World of Cutting and Welding – Urban Steel Expo (or USE for short) is the new hotspot for welding and cutting specialists. This new trade fair format will celebrate its first edition at the Messe Düsseldorf exhibition centre from 20^th to 23^rd April 2027.
