Nos procédés

Vaccum bonding

Halrai has developed an innovative process for the manufacture of the walls of its Kapalco vans. We have developed a table with a retractable cover where we insert the walls to bond. This structure is fitted with an air extraction system.  A vacuum bonded wall has all the layers and glue placed on a table and a vacuum is applied to press the glue and layers together…its a much more uniform process , our walls are light weight but extermly strong.

Welding

Our welders have more than 50 years of experience. They regularly participate in training sessions. Our reputation is forged from their expertise. Our ingenuity and know-how in the design and processing of metals combine to offer you the product that perfectly meets your needs. These are the welding proceses we exercise.

Shielded metal arc welding (SMAW) – also known as “stick welding or electric welding”, uses an electrode that has flux around it to protect the weld puddle. The electrode holder holds the electrode as it slowly melts away.

Gas tungsten arc welding (GTAW) – also known as TIG (tungsten, inert gas), uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an inert shielding gas such as argon or helium.

Gas metal arc welding (GMAW) – commonly termed MIG (metal, inert gas), uses a wire feeding gun that feeds wire at an adjustable speed and flows an argon-based shielding gas or a mix of argon and carbon dioxide (CO2) over the weld puddle to protect it from atmospheric contamination.

Fabrication

Halrai can depend on qualified machine operators. Their expertise in the field is recognized throughout the industry. We are proud to have the best! Our technicians have the knowledge to provide solutions tailored to your needs.

 

 12VDC and 110volt electrical systems

Halrai has expertise in power generation and electricity, as well as in the distribution and integration of electrical equipment within a mobile context and the conversion of service vehicles.

Halrai’s  experience in vehicle electrical and electronics is vast. We understand that the vehicles we upfit are required to perform on a daily basis with minimal downtime. We take no short cuts when it comes to electrical design and functionality. Our upfits will always come with a wiring diagram for any equipment we have added. We build our own panels and harnesses that can easily disconnect all of our added components from the chassis for ease of troubleshooting .
