REGAL TECHNOLOGY - WORKING WITH AND FOR OUR CLIENTS
The mission of Regal Technology Corp. is to team with our clients to assist them in getting the optimum benefit out of the explosion clad materials we supply to them. This starts at the very beginning when we initially receive an inquiry or quote request and continues through to the delivery of the finished product to our customer. After delivery, we continue to be available and willing to provide our clients with technical support as needed for our clad products. While the explosion bonding process appears to be relatively simple, the production of an explosion bonded product requires a significant number of carefully executed steps to insure a quality product is produced.
Inquiries and Quotations

Shear Test sample ready for testing
It is critical that all aspects of the explosion bonded product be correctly and thoroughly understood from the very beginning of the inquiry stage. Before responding, we carefully analyze each inquiry for
- Technical restrictions (i.e., issues relating to bondability, mechanical properties, size and weight)
- Potential metallurgical issues
- Code and specification requirements and interpretation (ASME/ASTM, client imposed)
- Testing and inspection requirements/procedures (pre and post bonding)
- Post cladding processing requirements.
If issues, incompatibilities, conflicts, etc. are noted, we will discuss and resolve these with the client before proceeding with the quotation.
Material Procurement and Pre-Bonding Processing
- Once a client purchase order is received, it is carefully scrutinized for completeness and correlation to the original quotation, for added requirements, changes, etc.
- Purchase of clad and backer materials (specify any supplementary requirements)
- Incoming inspection of clad and backer materials to correlate heat number markings to materials mill/test reports, visually inspect surfaces, measure flatness and thickness, etc.
- Surface grinding of clad and backer surfaces to be bonded
- Post grinding inspection for flatness, thickness and finish
This is obviously the most critical step of the process where control is absolutely essential.
- Based on the properties of materials being bonded, the parameters necessary to yield optimum bonding are calculated. From this the explosive system with the desired performance in combination with the corresponding standoff gap is selected.
- The clad and backer components along with the explosive container are then assembled for the cladding operation
- The cladding assembly is then placed at the shooting site, loaded with explosive and detonated
Packaged Parts ready for shipment
Following the explosion bonding operation, the clad part part undergoes a series of standard processing steps before it is shipped to the client. These include:
- Flattening - All clad parts are flattened and checked to insure they meet the requirements of ASME SA-20 and IEMA GuideNote 100.
- Stress relief heat treatment required on some combinations such as titanium and zirconium clads
- Inspection - Following flattening it is Regal Technology's standard procedure to 100% ultrasonically inspect the bond and material integrity of all clad parts per ASME SA578.
- Marking - Prior to packaging and shipping, each clad part is stamped on the backer surface per ASME Code requirements.
- Labeling - Labels providing detailed information and data about each clad part are affixed to the surface of the clad for easy identification and referencing upon receipt by our client.
- Packaging and Shipping - All clad parts are appropriately wrapped and prepared for safe shipment. A label, identical to the one described above, is also affixed to the exterior surface of the wrapped part for easy identification without unwrapping upon arrival at our client’s facility.
- Certification - A Certificate of Conformance complete with supporting documentation is supplied for each clad part.
- Administrative Quality Control - All records and data related to each cladding job are electronically stored both at Regal Technology and offsite for long term archival purposes.
Weld Prep with Clad Strip-Back
Explosion clad parts as supplied by Regal Technology typically are not in finished form. They may require additional fabrication steps to finish and incorporate into a finished vessel or structure. These may include various machining, forming (shell and head), welding, heat treatment and final inspection steps each of which may impact the performance characteristics of the clad part.
As a part of our effort to team with our clients to help them get the most out the clad products we manufacture for them, our personnel are happy to provide technical assistance as needed in association with these subsequent operations.
