Who are Svetsprocedur.se?
We are a company that can provide your organisation with recipes for welding in the form of welding procedures. For that reason, we have chosen to create welding procedures for a number of different brands, product names, weld geometries, thickness intervals and welding methods that are frequently used in the manufacturing industry.
The abbreviation WPQR, meaning Weld Procedure Qualification Record, is frequently used. This was previously called WPAR (Weld Procedure Approval Record).
Our objective is to provide manufacturing companies an opportunity to obtain welding procedures, on short notice and at low cost, in accordance with ISO 15612 (Standard Welding Procedure).
In addition, companies can also avoid the following
1. The uncertainty of creating procedures without knowing whether the result will be approved.
2. The cost of setting up the welding procedure and testing it. (Usually starts at EUR 1,500 or more)
3. Spending time testing and waiting for results. (Normally at least three weeks waiting for results).
Why use welding procedures?
The reason for using welding procedures is simple; Verified material and mechanical properties of the steel and the weld. If welding is not governed by welding procedures and WPSs (Weld Procedure Specifications), there is a risk of the material/weld becoming brittle, which may lead to the material cracking when used at low temperatures.
When are welding procedures required?
Welding procedures are required in e.g. the following instances:
1. Ironwork/structural steelworks carried out in accordance with EN 1090-2. (Standard welding procedures can be used for execution class EXC1, EXC2 and EXC3)
2. Certification of welding fabricators in accordance with ISO 3834.
3. When working on pressure vessels in accordance with the PED (EN 13445).
4. When working according to NORSOK standards.
5. Customer requirements.
NB: Always make sure that qualified procedures are not required, in accordance with ISO 15613 or ISO 15614.
