Pehea ka nui o kāu ʻike e pili ana i nā mea wili? Mai poina i ka huina nui! (I)

1. Pepa hao hao

ʻO ka pepa galvanized ka mea hoʻoheheʻe maʻamau. ʻOi aku ka haʻahaʻa o ka mahana hoʻoheheʻe o ka zinc ma mua o ka helu heheʻe o ke kila, no laila ʻoi aku ka maʻalahi o ka hana ʻana a me ka weld i ka wā wili. ʻOiaʻiʻo, ma muli o kēia, e loaʻa nā hemahema i ka pepa galvanized i ka wā welding. Ke hoʻomau mau nei ka zinc, e komo ka mahu i hana ʻia i loko o ka weld e hana i nā pores a i ʻole nā ​​​​pores. He kūpono no ka welding laser.

2. Ke kila kila

Lohe pinepine mākou i nā mea kila kila. ʻO nā mea wiliwili maʻamau, ʻo ia ka austenitic stainless steel, ferritic stainless steel, a me martensitic stainless steel.

1. Austenitic kila kila
ʻOi aku ka maikaʻi o ka hana kuʻilima Austenitic, liʻiliʻi thermal conductivity akā kiʻekiʻe absorption rate. Ke hoʻohana ʻia i ka welding laser, wikiwiki ka wikiwiki o ka welding a liʻiliʻi ka hoʻokomo wela. ʻOi aku ka hoʻohana ʻana o Austenitic stainless steel i ka Cr Ni series stainless steel welding operations, a ʻoi aku ka hoʻohana ʻana o ka welding laser e weld austenitic stainless steel, me ka pale ʻana i kona deformation a me ke koena.

2. Ferritic kuhiliʻole kila
ʻO nā mea maikaʻi o ka ferritic stainless steel ʻo ia kona paʻakikī nui a me ka ductility maikaʻi. I ke kaʻina hana kuʻi, he liʻiliʻi ka hopena. No ka laʻana, hiki i ka austenite a me ka martensite ke haki i ka wā wili laser, akā hoʻemi maikaʻi ka ferrite i kēia hiki.

3. Ke kila kuhiliʻole Martensitic
He mea ʻē paha ke kila kuhili ʻole Martensitic i nā mea a pau, no ka mea, ʻoi aku ka haʻahaʻa o kāna hana ma mua o ke kila kuhili ʻole austenitic a me ke kila kuhili ʻole ferritic. Hiki pinepine ka pohā anu i ka wā e hoʻohana ʻia ai ke kila stainless martensitic no ka wili, a ʻaʻole kūpono ka hopena wili. Hoʻohana ʻia kekahi mau hana welding me nā koi haʻahaʻa a me nā kumukūʻai, a ʻaʻole kiʻekiʻe ka pinepine o ka hoʻohana ʻana.

3. Ke kila kila

ʻO ke kila Alloy ka mea maʻamau i nā māwae anu i ka wā wili, akā ʻo kona pōmaikaʻi ʻo ia hiki ke hoʻopili pololei ʻia i ka lumi wela, a ʻoi aku ka paʻakikī. No kekahi mau noi me nā koi koʻikoʻi paʻakikī, ʻo ka wili kila kila he koho maikaʻi. No ka wili kila kila, hoʻohana nui ʻia ka welding laser. E hoʻohana ʻia kekahi mau hoʻoili kaʻa, ʻo ia hoʻi nā ʻāpana ʻenekini o nā mokulele, e wili i ke kila kila.
