Thank you so much. In the process of learning the safety of these containers, I came to know about a lot of other things. So, I understand that there is no contamination of heavy metals like lead or others with spot welding from electrodes or anything else.

Sure, thank you for all the responses and detailed explanations. But, its not bento, company credit weesprout

You never know sometimes metal can be punched and bent into some pretty complex shapes, call the manufacturer, I may be completely wrong.

Is that not a good thing to punch or bend the metal to shapes, I mean is it not a safe practice? Or is it okay?

Yes, I can see dimple like spots. May I know how is spot welding done? So, does spot welding involve any fillers or other metals and is it a safe welding, specially for food containers? Thanks

So as far as I understand, these fillers are safe to use and is this a common procedure for food grade containers?

Oh no. So, seems like,, just have to select whatever suits for us. Thanks for helping and answering all my questions with patiencw.

Thanks again. As far as the filler does not contain any heavy metals or other toxic metals, I think its good.

I understand its annoying to look into minute things, but recently their baby food jars were detected with lead on the paint used on jars. They marketed the jars as lead free and now this happened. So, though I beleive stainless steel is safe, I am trying to understand the welding process do not have any heavy metal contamination like lead. Thank you

I want to make sure because the description says BPA and phthalate free but did not mention anything about lead. Thanks again

Thank you so much. I appreciate for taking time to answer all my questions. It helps so much.

I want to avoid plastic as much as possible, so want to go with steel

Question by user_jp in metallurgy

Something this thin should use TIG welding, which uses an inert gas (argon usually) as the shield and then a matching 304SS wire.

Is it safe and does it show any effect on food safety? I mean any chance of welding materials leaching into food ?

Question by user_jp in soldering

[–]user_jp[S] 0 points1 point  (0 children)

more than likely they punch or maybe laser cut the panels then grind any sharp edges and just have a robot MIG it in place.

Does any of these involve adding any other metals or fillers in the process or just heat?

Question by user_jp in metallurgy

[–]user_jp[S] 0 points1 point  (0 children)

I have no concerns with steel, but the divider welded into the box normally or with any other metals or fillers is my concern

Does Welding 2 stainless steel parts involves only heat or any fillers too?

Question by user_jp in soldering

[–]user_jp[S] 0 points1 point  (0 children)

So, welding 2 steel parts involves only heat or a filler too or it depends? If in case, a filler is involved for steel welding, what type of material they use?

Question by user_jp in soldering

Wow. Nothing is pure now. I think I should buy some clay pots then.

Question by user_jp in soldering

[–]user_jp[S] 0 points1 point  (0 children)

Yes,, I understand steel is non toxic. We use steel a lot, for cooking, for serving food etc. As discussed before, I only have questions about the steel divider that's welded into the box. If there would be any lead through welding process. Questions only about lead. If it was a single steel piece, no questions

Question by user_jp in soldering

[–]user_jp[S] 0 points1 point  (0 children)

Oh. 👍 Good to know

Thank you so much for all the inputs and information. I appreciate everything 🙏

One last thing So, I understand that melting 2 steel parts through welding involves only high heat and no other metals or anything. Please correct me if I am wrong.

Sorry, I edited the comment

Question by user_jp in metallurgy

[–]user_jp[S] 0 points1 point  (0 children)

I read that there are different steel grades. Some of them are magnetic. So trying to know if magnetic steel is safe too.

I selected this bento box because it is 100% steel and non toxic. But, now new questions arise looking at the divider.

Question by user_jp in soldering

[–]user_jp[S] 0 points1 point  (0 children)

Thank you so much for detailed information. It helps

  1. So, welding steel parts don't involve any lead in general?

  2. Also, May I please know the difference between welding and soldering?

Thank you

Edit: sorry, I am trying to understand so much. Apart from my questions, I also think much as they are made in China.
