溶接熟練者も驚く、うそやろ!! (何でこの良さが分からないの)


ステンレスTIG溶接技能試験用バックシール治具、第二弾です。

アルミ材料の値上がりで無垢材からアルミフレーム材に切り替えました。

専門知識が有るものとして説明させて頂きます。

通常のバックシール治具はテストピース裏側を酸化させない為、Arガスを流し

裏ビードを酸化させな様な治具が必要だった。

≪説明≫

今までのバックシール治具は必要いりませんし、裏側にArガスも流さなくても完全にシールできます。

アルミ板とテストピースを挟むだけで、裏ビードは酸化もしないし、歪も少なくなります。

まさしく、素晴らしい革命的な治具で、きっと満足できるものです。

私は試験場で試験官の承諾をえて使用していましたが、40年前のことですので現在各都道府県

の試験場で使用しても良いか、確認を取っていただきたい。

その頃は試験場バックシール治具が有りましたが、各自、独自で製作した 治具を持参していました。


最近、試みたのですが1層で仕上がらないかと試してみた結果、大変良かったので参考までにお披露いたします。

《参考データー》

・開先角度:45°
・ルート面0 ドン付け
・溶加棒:2φか2.4φ
・電流:115A
・操作方法:ローリング工法
・歪:問題なし
・溶加棒は多めに断続的に入れる事

*、慣れない方は二層仕上げの方が無難かもしれません。
  二層目はシール効果がありませんので、裏ビードは焼けますが試験には問題ありません。

*、歪は画像でも確認できますが、殆ど歪んでいません(他者と出来栄えが違います)

参考までに、この冶具を使うことで溶接の知識や応用が増した事は事実であります。

溶接で分からない事や応用が知りたい方は連絡ください。

・親和力の強いチタンでも一発で良い結果が出ました。

最後まで読んで頂き有難うございます。

『おまけ、知識』

*、冷凍食品、自然解凍にもお役に立てればと思います。
*、トーチから出るArガスが開先の隙間から下のアルミ板にあたり跳ね返ったガスが裏波をシールするものである。
*、裏波が出すぎてもアルミとは融合しない(直流TIGではアルミ酸化被膜を破れないから) 
*、上の押さえ板はトーチローリング工法で、初心者でも簡単にローリング工法ができるように考えています  オールポジションで
   安定した溶接がかなえられます。
*、練習用テストピースも自作ですが、今回だけ1セット付の価格ですので直ぐ練習できます。

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters).

1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
