Products and Technologies

Aiming for "new frontiers" in welding technology

Special precision welding company

Sanitary piping for pharmaceuticals

●Achieved through specialized and skilled TIG welding techniques

*Welding types: TIG, dissimilar materials, thin to thick plates, brazing, composite welding, etc.
*Thickness: 0.2 to 100mm
*Processing materials: SUS, AL, copper, titanium, Permalloy, Hastelloy, etc.
*MAX size 1000 x 2000 mm, up to 1 ton in weight
*In-house production of integrated processes: from material procurement to machining, welding and inspection

Heat reflector

●Strict weld quality control and testing for Class 1000 compliance

(1) Ultrasonic cleaner completely removes fine dust (iron powder) prior to welding process.
(2) Even after the burn removal process following to welding, impurities (chemicals, etc.) are completely removed by an ultrasonic cleaner.

After airtight welding of ultra-high vacuum equipment, liquid nitrogen, cryogenic tanks, etc., complete testing will be conducted by use of exclusive testing equipment.

Large cavity parts requiring airtight welding can also be manufactured

Reliable quality! In-house testing equipment is fully equipped

Manufacturing large can parts

●The following test conditions have been built in-house for use in pressurized and depressurized environments.

Leak test: with He leak detector
Leak test: under water, air and gas pressure
Color check, leak test with air blow

Large can manufacturing

●Welding of all materials from thin to thick plate

*Capable to provide perfect welding quality with In-house improved TIG welding machine
*Large can parts are especially welded with minimal distortion.

NORTH HILLZ can also provide secondary processing for large can manufacturing.

Good at welding of dissimilar materials and composite welding

Tackling new welding techniques

Combined TIG and electron beam welding

●More than 20 different metal joining methods

*Capable to offer multiple welding methods including fiber laser welding, TIG welding, YAG laser welding, brazing, electron beam welding, and friction stir welding.

What is the best welding/bonding method?
NORTH HILLZ is ready to answer any questions from customers. Please feel free to contact them.

Welded parts of dissimilar materials

●Joining two metals with different melting points

*There are various ways to join dissimilar materials.
In heat exchangers, copper and stainless steel are joined. For vacuum parts, NORTH HILLZ is capable to handle very difficult joints such as ceramic to metal, glass to metal and etc.

NORTH HILLZ welcomes inquiries about any welding and tackles to develop their joining methods and technologies of new materials.
