Welcome back to the Spinweld blog! This time around, we’re looking at the quality assurance process we use as we work on your friction welding projects.
All companies will tell you about the high quality of their product. Friction welding companies are no different. It’s part of the sale, after all. At Spinweld, we pride ourselves on the amazing quality of our work. But how do you know we’re living up to that promise?
The answer is accountability. Spinweld partners with a third-party testing laboratory called Element. That partnership is the key to our success, and the way you know your friction welding project will be handled with the utmost professionalism at Spinweld.
Element is a global company that provides mechanical testing, inspection, and certification. They work across many industries to ensure compliance in both materials and products used. This ultimately provides safety, compliance, and fitness for use.
How are friction welding products tested for safety?
Most quality assurance for friction welding is done as the product is being made. This is known as “in process” testing.
Overall things that are looked for in friction welding quality assurance testing are:
- Machine temperature
- Forge force
- Friction force
- Rotation speed
- Axial displacement (Upset)
- Visual (weld curl, discoloring of metal, marring)
- T.I.R (Total indicator run out)
- Net material dimension
As you know, the beauty of friction welding is that you can join two materials that are not able to be welded traditionally. But before we can do that, we have to make sure those two materials are of good quality. During the R&D process there are many checks, measures, and tests that take place with Element assisting in some of those raw testing including:
- Chemical analysis
- Strength and hardness
Part of the process also includes testing for a certain number of failures, essentially to guarantee that the weld is holding. This allows Element and Spinweld to be absolutely sure that your product is going to be as strong as possible! Destructive quality control examinations commonly used for friction weldments include:
Non-destructive testing include:
- Ultrasonic testing
- Dimensional inspections
- Visual inspections
- Magnetic particle testing
- Pressure testing
- Radiographic, X-ray
- Liquid penetrant
- Eddy current
- Load testing
Spinweld also tests the environment in which the welding is taking place, considering:
- TESA Micro Hite, programmable, digital, height gage
- OPG 14″ Optical Comparator
- Dino-Lite Pro Digital Microscope
- Tachometer RPM Gage
- Pressure Test Gage
- Thermal Range Gage
- Polishing Machine
- Bench Centers
- Roll Out Tables
- Granite Surface Plate 8″x3’x5′, 4″x12″x18″, Gage Blocks, Gage Pins, Height Gages, Bore Gages, Micrometers Depth, Micrometer Bore, Calipers, Indicators, Thread Ring Gages, Thread Plug Gages, etc.
What kind of expertise does Element bring?
Element is a global company, with a presence in more than 30 countries. Over 6,700 experts work for the organization, and the experts who conduct friction welding testing hold essential certifications in Certification Scheme for Welding Inspection (CSWIP) and Personnel Certification in Non-Destructive Testing (PCN). Other certifications include Certified Welding Inspectors (CWI), Certified Welding Engineers (CWEng), and International Welding Engineers (IWE). Element’s CSWIP inspectors are qualified to 3.1 Welding Inspector and 3.2 Senior Welding Inspector levels with varying expertise.
Do all friction welding companies conduct quality assurance?
Many conduct standard or limited internal testing for quality assurance, but not everyone does. What makes Spinweld unique is that we work with the best of the best. With Element’s amazing worldwide presence and credentialed employees, we know we’re doing right by our customers and their projects.
With our access to these highly-trained professionals, our third-party quality assurance makes all the difference. When you bring a friction welding project to Spinweld, you know you’re getting a product that’s not only expertly crafted, but checked multiple times for safety and quality!
