Certified Quality and Innovative Processes
Discover how Asimer Group leads in specialized welding services, offering hardfacing processes and special contributions that enhance the quality of your products. Our Welding Department is committed to excellence (certified according to ISO 3834-2) and performs two key functions: repairs on cast parts (porosity or shrinkage in parts during machining processes) and special contributions (nickel base and cobalt base), providing solutions known for their surface hardness and certified quality. It is important to highlight that all welding processes are controlled with their corresponding NDT (Non-Destructive Testing), whether PT, MT, PM, and Rx, with PT Level II operators.

Welding Overlay
The welding overlay process involves adding material similar to the base material, ensuring a solid and durable bond. At Asimer Group, this process is carried out with precision to improve and repair fundamental components. All this is homologated according to UNE or ASME standards, depending on customer requirements.
Special Welding (Hardfacing Overlay)
We specialize in special contributions (Nickel Base and/or Cobalt Base) to confer high surface hardness to the end products. We work with a variety of materials, including steels and alloy steels, authentic ASTM stainless steels, A 743 martensitic steels, and duplex ASTM A995.
ISO 3834-2 Certificate
ISO 9001-2015 Certificate
Quality Certification - ISO 3834-2
Asimer Group is certified under UNE-EN ISO 3834-2, ensuring comprehensive quality control in all aspects of welded fabrication. This standard defines complete quality requirements for fusion welding of metallic materials.
Approvals and Welding Processes
With over 80 Welding Procedure Specification approvals in ASME or EN-ISO-15614 standards, we excel in meeting the most demanding specifications. Our welding processes undergo rigorous Non-Destructive Testing (NDT) required by the customer, including liquid penetrant, ultrasonic testing, magnetic particle testing, and hardness testing.
Welding Processes - Innovation in Action
At Asimer Group, we employ the latest advancements in welding processes, ensuring superior results. Our services include:
MIG (Metal Inert Gas): Perfect for quick and efficient joints.
TIG (Tungsten Inert Gas): Ideal for high-precision welds on delicate materials.
PTA (Plasma Transferred Arc Welding): Ideal for applications requiring high quality and durability, PTA welding combines precision and control in the fusion process.
Automatic Welding: We have automatic welding machines to guarantee precision and consistency in every joint.
Industry Experience
With years of experience, we have closely collaborated with industrial valves and firefighting equipment to provide personalized and efficient solutions.
- Commitment to Quality: Our processes and materials meet the industry’s most demanding standards.
- On Time Delivery (OTD) represents the most important indicator in ASIMER.
- Personalized Approach: Every project is unique. We work with you to understand your needs and tailor our solutions.
