Additional guidelines welding

At Bax Metaal, we handle the welding of your parts and assemblies into a strong, durable joint. Below you’ll find more about our welding capabilities.

MIG/MAG and TIG welding

For efficient and strong joints in steel, stainless steel and aluminium, we use MIG/MAG welding, including automated welding with our two Valk Welding robots. For precise and aesthetic weld work, we use TIG welding.

Submitting weld information correctly

Effectively submitting weld information to manufacturing companies is crucial to prevent production errors, ensure weld quality and comply with international standards (such as ISO 3834 or EN 1090). When technical drawings reach us, the weld information must be structured and unambiguous. This mainly happens via three key elements.

1. Welding standards and weld symbols on the drawing

The basic information is placed directly on the 2D engineering drawing according to ISO 2553 (or AWS A2.4 in America). Arrow line and reference line: indicate exactly where the weld must be placed. Seam or weld type: symbols for, for example, a fillet weld, V-groove or square butt weld. Dimensions: the effective weld thickness (a-height or z-height) and the length of the weld. All-round or partial welds: visual indicators (such as a circle at the joint) that indicate whether a weld runs fully around a profile.

2. WPS (Welding Procedure Specification)

For certified weld work, weld symbolisation alone is not sufficient. In that case we need a WPS (welding procedure specification). This is the ‘recipe’ for the welder and contains: Material and thickness: which types of steel, stainless steel or aluminium are being joined. Welding process: for example MIG/MAG (135/138), TIG (141) or MMA (111). Filler material: the exact type of welding wire or electrode and the diameter. Settings: current (amperage), voltage, welding speed and the type of shielding gas (including flow rate). Preheating / post-treatment: any thermal requirements to prevent cracking.

3. Digital transfer (MBD / PMI)

We increasingly work paperless via Model-Based Definition (MBD). Weld information is then stored as PMI (Product Manufacturing Information) directly in the 3D CAD model, for example in STEP or JT files.
