It is an indication, not a formal approval. The specialist assesses the formal questions: qualification ranges, acceptance criteria, releases and anything affecting safety or certification. Engineering work such as a WPQR programme, an on site inspection or fabrication support is always quoted separately, also with a subscription. Payment runs securely through Stripe. You can cancel monthly in your own subscription environment. The amounts shown are starting prices, excluding VAT. ## Enterprise and projects Several users, your own project environment, agreed response times or a dedicated specialist for your project? We arrange that with you personally. [Get in touch](/en/contact/) [06 29 72 37 91](tel:+31629723791) ## A question about a welding standard, a WPS or an inspection? Just ask it. You get a personal answer from a welding coordinator who has done the work, not from a salesperson.
