Additive manufacturing technology is usedto reduce the weight of products like spacevehicle

3D printer technology is originatedby this welding technology

Even in the space welding is necessary and special weldingtechnology is being developed

Friction Stir Welding FSW is relativelynew technology and its application isexpanding from aluminum to theother material including steel as well

One of the advantage of FSW isits flat surface after welded andis applied to the airplane for thepurpose of reduction of airresistanceEngines for space vehicle are usedunder the severe condition from lowestto highest temperature because of theuse of liquid oxygen and hydrogen asfuel

Huge number of fuel tubes should bewelded together by the welder withhighest skill‘Shinkai 6500’ is the advanced submarinewhich could dive into the depth of 6500m

In the 6500m deep see the submarineget the high water pressure and specialtitanium capsule is required to protectthe operatorTo realize the titanium sphere with highaccuracy and high quality the newtitanium welding technology wasresarched and developedUnder the sea the welding technology is still important and its skill requirethe special certification

Now a days thanks for the advanced steeltechnology the container ship is build with100mm thick high tension steel

Cost reduction of the welding thick steel isthe subject to be solvedVarious kind of welding technology isbeing developed

The new D runway of Hanedainternational airport wasconstructed with steel structure andit is exposed to the salt water

Those pipes used for the structureneeds the special weldingtechnology materialize highcorrosion resistanceWindmill energy generation plant isthe trend as the resolution for theglobal earth warming

Huge diameter steel pipe is made by bendingand weldingHigh efficient welding technology is required‘Shinkansen’ super rapid train is worldhighest train in operation

The streamlined head car is produced bybending and precise manual welding

Earth moving machines areexposed to tough condition andless fuel consumption byreducing the weight by hightension steel is key issues

In order to reduce the production cost robotwelding by harmonized moving control technologyis used and skilled human welding as well

Automobile industry is one of thebiggest fields of welding

Robotic spot welding is the majorproduction procedureThanks for the fiber laser technologylaser welding is also applied to theproduction line and laser brazing aswellTo produce lighter train variouskind of welding technology isapplied for the steel andaluminum body

Long steel rail is not endlessbar and is jointed by weldingon site

After the huge earthquake in Japan therequirement against the vibration forth forthe building construction have become higher

Buildings designed by steel structure isbecoming more popular in JapanTherefor keeping the welding quality high isthe important issue

You might use the glasses without any idea about weldingVery light and endurable glasses are very comfortable, which ismaterialized by using titanium and precise laser welding technology

Night scene of chemical plant isbeautiful for its brilliant illumination

The welding to connect the pipeline isa very big market for welding worldand controlled by specific certification

‘Sky tree’ the new land mark of Tokyois 634m high and much higher thanprevious land mark ‘Tokyo Tower’‘Sky tree’, such a high tower isrealized by applying the steel pipestructure

The pipe welding technology in thefactory was one of the key factor andespecially in situ welding required highlyskilled welder to weld on the highestplace

Light steel structured house is one of thesolution for the high endurance in thefield with frequent earthquake

Most of the steel structure iswelded in the factory with highquality control system by monitorusing IT considering traceability

JWES has 19 committees to develop newwelding technology which is used for the specificcommon industry field and strive to widelyimplement the technology to the field in orderto contribute to the societyOne of the biggest task for JWES is to standardize the developed technologyJWES is ISO member and ISO is one of the target of standardization‘JIS’ Japan Industry Standard is widely used standard not only in Japan but alsoin the Asian countries‘WES’ Welding Engineer Standard is JWES own standardIn order to introduce the new technologyJWES publishes the standards and the trainingtexts

Training curriculum or seminar is importantto widely introduce the new technology
