EN ISO 3834 Standards for Welders and Engineers
02.02.2023
The EN ISO 3834 standards are a set of quality requirements that cover welding activities. These standards, which include EN ISO 3834-2, EN ISO 3834-3, and EN ISO 3834-4, apply to all types of welding processes used in the industry.
In this blog post, we'll break down what each standard means for welders and engineers. 

EN ISO 3834-4 “Elementary Quality Requirement” 


This standard is intended for engineering and fabrication projects that require basic welding processes with low complexity. It covers all essential elements such as:
  • personnel qualification,
  • equipment inspection and maintenance,
  • documentation control, etc., that are necessary to ensure safe operation.

Any welding process that falls under this standard should meet the requirements of the relevant national or international codes. 


EN ISO 3834-3 “Standard Quality Requirement” 


This standard is primarily intended for engineering and fabrication projects requiring more complex welding processes with higher levels of risk.

It defines the quality system requirements needed to ensure product conformity and safety.

This includes:

  • personnel qualification requirements,
  • inspection and testing activities,
  • documentation control,
  • process control,
  • traceability of materials; etc., that should be followed during manufacturing operations.

It also specifies additional safety measures such as fire protection during welding operations. 


EN ISO 3834-2 “Comprehensive Quality Requirement” 


This standard applies to both welders and engineers who need an extensive quality system that meets stringent specifications in areas such as:
  • design review,
  • personnel qualification requirements,
  • process control activities including preheating treatment procedures,
  • inspection and testing activities to verify product conformity before shipment or delivery.

This is essential for ensuring the safe operation of the products manufactured using these standards.

Additionally, it requires performing non-destructive tests such as radiographic or ultrasonic examination on certain parts or components to detect any hidden defects before final approval of the products or services provided by these standards. 


Conclusion: 


The EN ISO 3834 standards provide welders and engineers with comprehensive guidelines on how to ensure product safety through the proper implementation of quality systems at their workplaces.

They provide clear guidance on personnel qualifications, process control activities such as preheat treatment procedures, inspection & testing activities before shipment or delivery, etc., that must be followed to meet these standards' high-level expectations regarding product conformity & safety.

Adhering to these standards will help prevent costly mistakes due to faulty products or services caused by inadequate quality systems implementation at one's workplace thereby ultimately resulting in better customer satisfaction & trust in one's business offerings!
